The Mini Thumb Dactyl Keyboard

This is a fork of the Dactyl-ManuForm, a parameterized, split-hand, concave, columnar, ergonomic keyboard.

The Dactyl-Manuform is a fork of the Dactyl with the thumb cluster from ManuForm.

My fork contains below versions of keyboard models:

Mini-Thumb-Dactyl

File: mini_thumb_dactyl.clj

I'm comfortable with the concave curve of Dactyl-ManuForm keyboard. But I don't need so many thumb keys. This version reduces thumb keys to three on each hand.

Printable area requirement for mini-thumb-dactyl 5x6 is 16cm x 14cm, or delta printer diameter 18cm.

I removed RJ9 connector hole in this version, because it's difficult to buy RJ9 connector. Use 3.5mm earphone jack or direct cable wiring instead.

Enhanced Dactyl-ManuForm

File: dactyl.clj

It's basically the original Dactyl-ManuForm with some enhancements, including:

  • Printable bottom plate
  • Add hole to mount reset botton (Some manufactory's Pro Micro requires double reset to flash firmware)
  • Replace Teensy holder with Pro Micro holder

Dactyl-ManuForm, thumb part printed separately (WIP)

File: dactyl_split.clj

The model might be larger than printable area of some 3D printers. I tried to separate the thumb part from main body of the keyboard to make it smaller.

It's isn't fully done and I gave it up because I turned to the mini-thumb-dactyl. Above enhancements aren't added into this version.

Assembly

Generating a Design

Setting up the Clojure environment

Generating the design

  • Run lein repl
  • Load the file (load-file "src/dactyl_keyboard/dactyl.clj") (change file name for other version)
  • This will regenerate the things/*.scad files
  • Use OpenSCAD to open a .scad file.
  • Make changes to design, repeat load-file, OpenSCAD will watch for changes and rerender.
  • When done, use OpenSCAD to export STL files

Tips

Printing

Print the generated models: left and right. There are also models for bottom plate: left-plate, right-plate.

Fix the model before printing if it has defects. I use Netfabb Free to and it's automatically done.

Wiring & Firmware

Please read the guide: How to Make a Dactyl Manuform Keyboard
