CHANGELOG.md

Change log

This log follows the conventions of keepachangelog.com. It picks up from DMOTE version 0.2.0, thus covering only a fraction of the project’s history.

Unreleased

Changed

• The default type of microcontroller has changed, from promicro to rpi-pico.
• Modified the design of keycaps on the Concertina, using and matching the full set of caps bundled with dmote-keycap v0.8.0.
• The port type custom has been renamed to custom-cuboid.
• Started using YAML anchors in bundled configuration files for deduplication. This is not a change in application logic, API or design; the YAML parser expands each reference to the same effect as before.

Added

• The port type custom-cylindroid. This enables round ports.
• The MCU type rpi-pico.
• Bundled designs:
  • Added a kailh.yaml file for PG1511-style switches on a Concertina.
  • Added an encoder folder for rotary encoders on a Concertina.
• Conical tops for the bosses of heat-set inserts. This is intended to prevent slicing software from adding support material inside the hollows.

Fixed

• Fixed problems related to keycap size by upgrading to v0.8.0 of the dmote-keycap library.

Version 0.7.0 - 2021-04-10

Changed

• Switched the default build target (with GNU Make) from the DMOTE to the Dactyl-ManuForm.
• More precise control.
  • Replaced the way that key-cluster walls are measured. Instead of separate settings for bevel, parallel and perpendicular, there is now only one setting, called segments, with more power, including the ability to vary size (was thickness) by segment.
  • Integrated bottom-plate fasteners and their bosses with the flanges section of configuration introduced in v0.6.0. This invalidates most of the bottom-plate settings that were previously available under main-body, central-housing and wrist-rest, but adds more power: Customizable boss segments richer than those of keys, heat-set inserts universally available, the option of different kinds of screws for different bottom plates (e.g. shorter in wrist rest) etc.
• Fewer side effects.
  • Disabled responsiveness to predicted resting key clearance by default. This can be re-enabled with a new parameter (use-key-style).
  • Disabled responsiveness to flange screw size (including the “new” bottom-plate flanges) for making flange bosses.
  • Changed the meaning of the at-ground parameter for tweak nodes, so that hulling to ground is no longer a side effect of it. Added a corresponding, explicit to-ground parameter.
• Made false the default value of all Boolean parameters.
  • Stopped including arbitrary shapes for tweaks in above-ground contexts by default.
  • Replaced positive for arbitrary shapes with an inverted cut parameter.
  • Set include-threading for bolts to false by default.
• Completed migration from long-form names for the points of the compass, like north, to short-form names, like N. This leaves only short forms, so the distinction itself is abolished.
  • The shorter names are now used for nested configuration by key.
  • The shorter names are used for fasteners through the rear housing, under a new section (sides).
  • The longer names, previously optional for MCU shelf sides, are no longer permitted there.
• Moved and replaced some (other) parameters:
  • Made the central-housing → adapter → receivers → thickness → bridge parameter a section, with its function inherited by tangential in that new section.
  • Renamed MCU shelf sides to rim to prevent confusion with the adjacent bevel section of parameters, which is indexed by sides (compass points).
  • Replaced central-housing interface settings for adapter → offset with a segments map, as for key-cluster walls and flange bosses.
  • Replaced the positive property of tweaks (default true) with a cut property (default false). Its effects are identical, but the values are inverted.
  • Migrated to scad-app v1.0.0, which includes renaming the minimum-face-size parameter to minimum-facet-size, even in the DMOTE configuration interface.
• Dropped support for arbitrary YAML inclusions through GNU Make.
• Bundled designs:
  • Stopped including threading on bolts in most models, for faster renders and reduced sensitivity to printer accuracy.
  • M3 screws instead of M4 in config/base.yaml.
  • DMOTE:
    • Slightly thicker bottom plate.
    • Smaller bosses for screws attaching the wrist’s bottom plate.
  • Concertina:
    • Reduced to one size of keycaps.
    • Improved USB B port and MCU shelf.
    • More tactile, variegated thumb clusters.
    • Pinky-finger and thumb-cluster keys closer.
    • Deeper, fewer holes through bottom plate.
  • Slight tuning of DFM settings for more common printers and more modern slicers.

Added

• Added support for Kailh’s PG1511 series switches and similar MX clones without lateral recesses in the lower body.
• Added a nominal clearance parameter to make it easier to design for multiple different types of switches and keycaps.
• Added support for custom key mounting plate size.
• Added several new optional behaviours for arbitrary shapes (reflect, to-ground, shadow-ground, polyfill).
• Extended the concept of a combined bottom plate to include the central housing.
• Added a parameter for central-housing interface fastener-receiver radial thickness.
• Added thinning of central-housing adapter lips based on DFM error setting.
• Added precise control over segments for each node on the central housing interface’s adapter.
• Added a parameter for disabling all threading to improve low-resolution rendering performance.
• Added a tutorial for getting started designing from scratch.
• Bundled designs:
  • Added a configuration fragment for removing the rear housing of the DMOTE.

Fixed

• Made the application of the DFM error-general setting to bolts more consistent.

Migration guide

Here is an example of adaptation from the old wall-building syntax to the new:

-      parallel: 4
-      perpendicular: -16
+      segments:
+        "2":
+          intrinsic-offset: [0, 4, -16]

That is an excerpt from config/macropad/base.yaml, preserving the shape of the wall.

To preserve the old behaviour of a tweak node that should affect the keyboard case body, add above-ground: true to it. Where you had positive: false, replace it with cut: true. Where you had at-ground: true, replace it with to-ground: true.

Migrating bottom-plate settings is a lot more complex, owing to the volume of changes. Please inspect bundled configurations.

Version 0.6.0 - 2020-09-09

Changed

• Moved and replaced some parameters:
  • The case section of parameters was renamed to main-body to avoid ambiguity with respect to other bodies, a new concept.
    • The top-level parameter split was both moved into the main-body section and renamed to reflect to avoid misleading the user about how it interacts with the new central-housing feature.
    • The case-side style of mounting wrist rests was similarly renamed to partner-side, and plinth-side to wrist-side.
    • The tweaks parameter has moved out of main-body to the top level, because it can now be used for other bodies.
  • Multiple sections for anchoring have been renamed from position to anchoring to reduce ambiguity with respect to bodies.
    • Parameters named corner have been renamed to side. This is because they now take codes for cardinal compass points as well as actual corners.
    • The single offset parameter has been split into intrinsic and extrinsic parameters.
    • The parameter governing how to source the angle of fasteners for a wrist rest mount has been renamed from anchoring to authority to remove ambiguity.
  • Parameters for key-cluster walls have been restructured.
    • Parameters formerly sorted under side-specific settings have been promoted to nest directly under wall and can now be used without selecting a side.
    • As a consequence of more flexible selection criteria, the bevel setting can now be side-specific.
    • Wall extent is now strictly numeric. Extending a wall to ground is governed by the new parameter to-ground and can now be done from any segment, no longer just segment 4.
    • The vertical segment sequence for key walls has been shortened and simplified. Wall thickness has been expanded into three dimensions, replacing three parameters under main-body: key-mount-corner-margin, key-mount-thickness and web-thickness.
  • All parameters governing individual properties of threaded bolts have been removed in favour of more powerful new parameters based on options exposed by a new library (scad-klupe) that draws bolts for the application. This change provides greater freedom to choose different bolt head types, partial threading, no threading (with a diameter suitable for tapping holes manually) etc.
  • The connection section has been replaced by a general ports map.
  • Some parameters governing the mounts of wrist rests have changed to strengthen the tweaking system.
    • The fastener amount parameter and height section have been replaced by a list of heights, no longer requiring even spacing by an increment (pitch).
    • The aliases section has been moved up one level, out of blocks.
    • Parameters governing nut pockets and bosses have all been removed. These parameters are replaced by a stronger tweak subsystem where you can name individual nuts and target them as negative space, creating pockets and bosses more freely.
    • The angle parameter has changed in meaning by a quarter turn, generally making configured angles smaller and easier to reason about, as well as putting mount width on the x axis for easier, more consistent tweaks.
  • Heat-set inserts for attaching bottom plates are no longer a separate style. Thus the inserts option has been removed from the main-body → bottom-plate → installation → style parameter and replaced by a new include parameter, governing the same feature independently of style.
• Removed much of the special treatment of the rear housing, no longer needed.
  • Removed the automatic webbing to key mounts.
  • The two parameters named prefer-rear-housing and their associated functionality, and the cluster parameter, were all removed, having been obviated by normal placement in relation to a wide range of anchors.
  • The raise parameter for connection has been replaced by an extension of the concept of vertical segments to the rear housing.
  • Removed into-nook, which automated some fine tuning for placing ports and MCUs inside the rear housing. This has been obviated in part by the corner-to-side change, which allows the user to target an edge rather than a corner of the rear housing, and in part by the extension of segments on the rear housing to include segment 2, referring to floor level beneath the walls.
  • More direct and exact control of rear-housing size, thickness and bevels, using new parameters.
• MCU supports have changed, gaining more power but losing some ease of use, to work better with the option of central housing.
  • The default orientation of the MCU PCB has changed, from standing on its long edge to lying flat.
    • In the Dactyl-ManuForm model, the MCU now lies flat, whereas in other pre-v0.6.0 bundled build targets, it’s still on its long edge because of accompanying changes to the configurations.
  • The MCU support style parameter was removed.
    • Instead of lock and stop existing as mutually exclusive styles, with the requirement of a key mount as the anchor for a stop, stop has been removed, named points on or in space around the MCU can now be connected using tweaks, and such a grip can be freely combined with a lock. See the Dactyl-ManuForm’s mcu-gripper.yaml for an example of how to use tweaks to replace a stop.
  • mcu → support → height-factor was moved to mcu → support → lock → width-factor.
  • mcu → support → lateral-spacing was moved to mcu → support → lock → plate → clearance.
• Some default values have disappeared altogether.
  • When anchoring a feature to a key mount, there is no longer a default value for the vertical segment of the key mount. The previous default was 3.
  • The default side (previously corner) of a target anchor is now nil (YAML: null or omission), meaning the centre (no side).
• Whether or not anchoring one feature to another imposes rotation is now more consistent and more directly controllable.
  • The MCU's rotation parameter has been removed in favour of richer general anchoring options.
  • 2D features that stick to the floor now get less special treatment and no longer take 2D offset coordinates.
• The default size of a tweak has changed from the size of a key-mount corner post to a nodule of 10⁻⁹ mm³, effectively a mere point. This matches the way that the rear and central housings, and some other features, are now drawn: As polyhedra made up of points rather than bodies with volume. This change was precipitated by moving key-mount thickness control out of its privileged position on main-body.
• The alcove generated for the front end of an MCU PCBA now uses the general DFM setting (error-general). The mcu → margin setting was removed.
• Anchors for bottom-plate mounting screws no longer have domed caps by default. These are still available but are governed by a new parameter. Domes were made optional to make it easier to tap threads rather than print them, and use longer screws than was originally intended.
• Mounts for wrist rests no longer have peaked caps by default. Instead, tops are bevelled like the sides, and the body of the mount has its nominal size at its base instead of at its top only, to help with tweaking.
• The foot-plates feature has been removed. Its functionality is now relatively easy to replicate with secondaries and tweaks.
• File names have changed where they correspond directly to bodies.

Added

• Documentation:
  • An execution guide, as a new document branched off from the introduction.
  • A general guide to concepts in the configuration layer.
  • A guide to anchoring parameters.
  • A guide to arbitrary shapes.
  • Tables of content in auto-generated documents.
  • Stock descriptions of recurring parameters.
• Support for a number of different types of MCUs beyond the Pro Micro: Common Teensies as well as the Elite-C and Proton C.
• A formal concept of bodies, making it possible to choose which OpenSCAD output file to target for a given tweak etc.
  • Central housing, a new feature adding a body separate from the main body.
  • Custom bodies.
  • Flanges: Arbitrarily positioned screws for connecting custom bodies to their parent bodies.
• Improved anchoring.
  • Homogeneous anchoring parameters, including new intrinsic and extrinsic translation and rotation of all anchorable features.
    • Full anchoring parameters for key clusters, wrist-rest mounts etc.
    • The ability to preserve orientation in anchoring without working via a secondary.
  • Anchoring to the MCU PCBA.
  • Anchoring to a wider array of the parts of a key mount, including different sides of its wall, using cardinal and intercardinal compass points, whereas before, only points intermediate between cardinals and intercardinals could be used.
• The by-key section of parameters has become more flexible. It is now possible to influence all keys on a row, without duplicating settings for all columns in that row.
  • sides is now a selection criterion just like clusters, columns and rows, matching the general strengthening of the concept of sides in this version.
• An MCU shelf. This type of MCU support corresponds directly to the Dactyl-ManuForm’s teensy-holder object and is therefore not new, but it has some parameters to extend its functionality.
• A new backing-thickness parameter to help control how far way from an MCU lock its fastener will extend.
• Support for an arbitrary number of ports.
  • Support for standard types of ports, including different USB connectors and a modular connector (616E for 4P4C, previously emulated in configuration).
• Extensions to bottom plates for projections of the anchors used to fasten such plates to the case. This restores a feature of the upstream Dactyl-ManuForm.
• Enhancements to tweaks.
  • Negative tweaks for subtracting material. So far, these are only used for 3D tweaks to the main body and central housing but they could easily be extended to wrist rests and bottom plating.
  • The ability to target ports, including port holders, and the plate of an MCU lock, including a set of vertical segments. The rear housing has also gotten vertical segments.
  • Intrinsic rotation.
• Support for specifying sizes with less than 3-tuples.
• Support for specifying angles with mathematical formulae using π.
• A size property of secondaries, for terser tweaks.
• The ability to override specific coordinates for secondary named positions.
• A GNU Make target for the Dactyl-ManuForm.

Fixed

• More accurate and printer-friendly spaces for the wings on ALPS-style switches.
• Respect for key spacing settings without curvature.
• Fixed a regression that made the interior of case walls too thick.
• Made transpile.sh sensitive to configuration changes again.
• A more categorical fix for dmote-keycap parameter support, achieved by migrating that library’s parsing logic into the library itself. See version 0.5.1.
• Better placement of heat-set inserts. More careful interaction with a plate offset and with the bottom plate.
• Slightly improved user feedback when configuration files contain structural problems.

Developer

• Improved REPL support.
• New namespaces:
  • anch, collecting collectors of anchor points.
  • body, collecting logic specific to the new concept of bodies. Code previously in the single-file body module, but not specific to the main body, moved into the key and mask namespaces. The key namespace branched into a package of several modules as a result. A new assembly module within body took the composition functions from core.
  • compass, gathering code from generics and matrix with refactoring to improve the compass metaphor for feature placement.
  • cots, gathering information on commercial off-the-shelf goods.
  • mask, taking the above-ground mask function out of the main body module, and the bottom-plate masks too.
  • mcu, breaking MCU features out of auxf.
  • misc, which collects everything that remained of generics after compass code moved out. This makes two misc modules.
  • poly, collecting helper functions for making polyhedra.
  • tweak, breaking tweak plating out of body and bottom.
  • Split the schema module into separate modules for parsers, specs and reusable stock structures.
• The parameter interpreter now bans nil only as a function of explicit validators, no longer categorically.
• Removed functions from the derived user configuration.
• Added a folder of configuration files under test/config for manual regression testing.

Migration guide

Compare versions of config/dmote/base.yaml to see how to migrate your old configuration files. Salient points:

• Move a setting like parameters → wall → north → extent into sides → north → parameters → wall → extent.
  • Replace a full extent with 3 and set to-ground to true.
• Replace each fasteners → diameter with a bolt-properties → m-diameter setting, and each bolt length setting with bolt-properties → total-length or threaded-length, depending on whether you want the head to count towards length. For the MCU lock, the term is fastener-properties to avoid confusion with the bolt of a lock.
• To compensate for the changed default orientation of the MCU in an existing custom configuration, use the moved intrinsic-rotation setting for your MCU support, with the value [0, π/2, 0].
• Rename corner parameters to side.
• Rename anchoring → offset to intrinsic-offset, unless you want to make sure it happens in global vector space, in which case rename it to extrinsic-offset.
• For features that were not previously rotated with their anchors and should not be, add preserve-orientation to anchoring.
• Remove connection and add equivalent settings to the new ports map.

Version 0.5.1 - 2019-10-16

Fixed

• Added a parser for one more of dmote-keycap’s parameters (supported), thus allowing supports to be turned off for keycap models rendered through this application.

Version 0.5.0 - 2019-07-21

Changed

• Secondary aliases (secondaries) are now a map and case tweaks are likewise nested underneath a layer of names. Both of these structural changes add power to the configuration layer, reducing the need for duplication of data.
• Fixes that make the height of the case easier to manage constitute changes to previous behaviour:
  • Key mounting plates, which were previously located immediately on top of the nominal position of each key, are now below the nominal. In other words, key mounting plates have dropped down by the thickness of the mounting plates. This means that, on a completely flat keyboard, the configured height of each key mount is now the height of the case.
    • When you change key mount thickness, the difference is now internal to the keyboard and will no longer affect the relative positions of the switches.
    • To match this change, mount thickness is no longer a factor in computing curvature. This in turn affects the nominal positions of keys. It effectively recalibrates the scale of matrix separation, correcting it so that the default value of value of zero is more likely to create a good design.
  • Webbing and case walls etc. are (still) governed by key mounts, so they have also dropped down.
  • Similarly, the configured height of the rear housing is now its actual height, not the centre height of the cuboids that make up its corners.
• Moved bundled YAML.
  • The entire resources/opt folder is now at config.
  • Most of resources/opt/default.yaml has been renamed (to config/dmote/base.yaml) and is now less privileged.
  • A simple make has the same effect as before but passes more arguments to achieve it. Without arguments, the Clojure application now describes an unusable single-button keyboard.
• Changes to the bundled 62-key DMOTE configuration:
  • Switched from M3 to M4 screws for attaching the bottom plate and for locking the MCU PCB in place. This makes for quicker previews and easier printing.
  • Switched from flat to conical points for bottom-plate fasteners, just so the holes are easier to slice without getting interior supports.
  • Minor tweaks, like renaming the maquette-dsa style to default and removing a secondary anchor obviated by new controls for rear-housing post thickness.
• Replaced the nut boss in an MCU lock bolt with printed threading of the hole.

Added

• Key mounting plates responsive to key unit-size for ease with oblong keys.
• A bundled 12-key macropad configuration, mainly as an object lesson.
• A split parameter at the highest level. This is false by default and absent in config/base.yaml, to enable macropads and relatively regular keyboards. It’s true in config/dmote/base.yaml.
  • An include parameter for the connection metasocket. This is false by default and true in config/dmote/base.yaml. Its effect is contingent upon the split parameter.
• An include parameter for MCU PCBA support. This is false by default and absent in config/base.yaml, mainly to enable tutorials where the MCU support does not pose a distraction, and partly to allow custom alternatives to the supported styles.
• More finely grained control for dimensions previously governed by general case webbing thickness.
  • New parameters for rear-housing wall and roof thickness.
  • A new parameter for connection socket wall thickness.
• A new implementation of the solid style of wrist rest attachment, with a bundled example configuration powered by the new structure of secondaries and case tweaks. In the example, the case and wrist rest are one piece of plastic. In a previous implementation, removed in version 0.3.0, the two were separate pieces that snapped together, which put more requirements on the shape of the case and was not useful enough.
• A new DFM parameter, fastener-plate-offset, for tighter holes through bottom plates.
• A new bundled configuration fragment, config/dmote/mx.yaml, imposing MX-style switches on the DMOTE.
• More features added to config/dactyl_manuform/base.yaml, reconstructing part of the classic upstream shape as a configuration.
• A primitive means of combining YAML files by passing them as targets to Make. This does not work as intended and may be removed in future.

Fixed

• Renamed a file (from aux to auxf) to work around file system restrictions inherited from MS DOS into current versions of Windows.
• Corrected placement of wrist-rest fastener anchors for the thickness of the bottom plate.
• Fixed a bad function call for stop-style MCU support.
• Slightly more accurate models of switches.

Developer

• In the interest of versatility, the Clojure code no longer refers to any YAML files. Instead, the default configuration values that are built into the code itself are slightly richer, to prevent crashing without YAML files.
• Restructured the makefile, renaming some of the phony targets (e.g. visualization to vis) and removing others for the present. make all no longer exercises as much of the code.

Version 0.4.0 - 2019-06-06

Changed

• Moved and replaced some parameters:
  • Both the keycaps and switches sections have been replaced. There is now a keys section that defines one or more styles, as well as a key-style parameter in the nesting by-key section of parameters.
  • The to-ground key for case tweaks has been renamed to at-ground for clarity with respect to a new above-ground key.
  • The general error parameter for DFM has been renamed error-general.
• Changed default.yaml from a 60-key layout with a user-facing 1-key aux0 cluster to a 62-key layout (31 on each half) with a 2-key aux0 cluster at the opposite corner and facing away from the user.

Added

• Support for multiple, named styles of keys.
  • This includes some with enough detail on the keycaps to permit printing. These printable models are now among the outputs of the application.
• Improved case tweaks.
  • Tweaks are no longer restricted to key aliases.
    • Any named feature can be used in a leaf node.
    • It is no longer necessary to specify a corner or segment for a tweak.
  • Tweaks can now target bottom plates without impacting case walls. There is a new configuration key for this (above-ground, which must be turned off to see the new behaviour).
  • Added a secondaries parameter for named features that are just points in space, placed in relation to other named features. Used in tweaks, these secondaries give greater freedom in shaping the case.
• Added a resolution section to the parameters.
  • By default, already-existing resolution parameters (both of them are for wrist-rest pads) will be disabled by a default-negative new include parameter in the new section.
  • The new section also provides a means of rendering curved surfaces elsewhere in more detail.
• Added a thickness parameter specific to the threaded anchors for bottom-plate screws.

Fixed

• Improved the fit of a bottom plate for the case, at the cost of greater rendering complexity.
• Reduced risk and impact of collision between nut bosses built into the rear housing and the interior negative of the socket for connecting the two halves, by reducing the thickness of one part of the negative.

Developer

• Took advantage of new developments in general-purpose libraries:
  • Outsourced file authoring to scad-app for improved CPU thread scaling, rendering feedback and face-size constraints.
  • scad-tarmi lofting replaced pairwise-hulls and triangle-hulls.
  • scad-tarmi flex functions obviated several separate functions for object placement and reasoning about that placement.
  • scad-tarmi coordinate specs replaced locals.
  • Featureful dmote-keycap models replaced internal maquettes.
• Made the rosters of models and module definitions reactive to the configuration.
  • Converted keycaps and switches to OpenSCAD modules.
• Changed the merge order in the reckon-from-anchor function to make secondaries useful in tweaks.

Version 0.3.0 - 2019-02-18

Changed

• Moved and replaced some options:
  • Dimensions of keycaps have moved into nestable parameters under by-key.
  • key-alias settings have been merged into anchor. anchor can now refer to a variety of features either by alias or by a built-in and reserved name like rear-housing or origin. In some cases, it is now possible to anchor features more freely as a result.
  • Moved case → rear-housing → offsets into case → rear-housing → position.
  • Moved case → rear-housing → distance into case → rear-housing → position → offsets as south.
  • Renamed the key-corner input of case → foot-plates → polygons to corner.
  • Removed the option case → rear-housing → west-foot in favour of more general foot-plates functionality.
  • Removed wrist-rest → shape → plinth-base-size in favour of settings (in a new spline section) that do not restrict you to a cuboid.
  • Removed wrist-rest → shape → chamfer. You can achieve the old chamfered, boxy look by setting spline resolution to 1 and manually positioning the corners of the wrist rest for it.
  • Moved wrist-rest → shape → lip-height to wrist-rest → shape → lip → height.
  • Moved wrist-rest → shape → pad → surface-heightmap to wrist-rest → shape → pad → surface → heightmap → filepath.
  • Substantial changes to wrist-rest → fasteners, which has been castled to wrist-rest → mounts and is now a list.
• Removed the implementation of the solid style of wrist rest attachment. This was reimplemented in version 0.5.0.
• Removed the option wrist-rest → fasteners → mounts → plinth-side → pocket-scale, obviated by a new generic dfm feature.
• Renamed the ‘finger’ key cluster to ‘main‘.
• As a side effect of outsourcing the design of threaded fasteners to scad-tarmi, the flat style of bolt head has been renamed to the more specific countersunk.
• Removed create-models.sh, adding equivalent functionality to the Clojure application itself (new flags: --render, --renderer).
• Added intermediate scad and stl folders under things.
• Split generated documentation (options.md) into four separate documents (options-*.md).

Added

• This log.
• Support for generating a bottom plate that closes the case.
  • This includes support for a separate plate for the wrist rest, and a combined plate that joins the two models.
• Improvements to wrist rests.
  • Arbitrary polygonal outlines and vertically rounded edges, without a height map.
  • Tilting.
  • Support for placing wrist rests in relation to their point of attachment to the case using a new anchoring parameter.
  • Support for multiple mount points.
  • Support for naming the individual blocks that anchor a wrist rest.
  • Support for placing wrist rests in relation to a specific corner of a key. In the previous version, the attachment would be to the middle of the key.
  • Parametrization of mould wall thickness.
  • Parametrization of sprues.
• Support for naming your key clusters much more freely, and/or adding additional clusters. Even the new ‘main’ cluster is optional.
  • Support for a cluster parameter to case → rear-housing → position. The rear housing would previously be attached to the finger cluster.
  • Support for a cluster parameter to case → leds → position. LEDs would previously be attached to the finger cluster.
  • Support for anchoring any cluster to any other, within logical limits.
• Parametrization of keycap sizes, adding support for sizes other than 1u in both horizontal dimensions, as well as diversity in keycap height and clearance.
• Support for a filename whitelist in the CLI.
• Support for placing foot-plates in relation to objects other than keys.
• Support for generic compensation for slicer and printer inaccuracies in the xy plane through a new option, dfm → error.

Fixed

• Improved support for Windows by using clojure.java.io/file instead of string literals with Unix-style file-path separators.
• Strengthened parameter validation for nested sections.

Developer

• Significant restructuring of the code base for separation of concerns.
  • Switched to docstring-first function definitions.
  • Shifted more heavily toward explicit namespacing and took the opportunity to shorten some function names in the matrix module and elsewhere.
• Added a dependency on scad-tarmi for shorter OpenSCAD code and more capable models of threaded fasteners.
• Rearranged derived parameter structure somewhat to support arbitrary key clusters and the use of aliases for more types of objects (other than keys).
• Removed the new-scad function without replacement.
• Removed a dependency on unicode-math. The requisite version of the library had not been deployed to Clojars and its use was cosmetic.
