Edit btmnfld.FCStd using FreeCad.
I am by no means a FreeCad expert, so I'm sure its built suboptimally.
Expect slow working with the files bc. of the many crude edits.
Should anyone want to do alterations i would advice simply "building on top" instead of going back the chain of events to prevent having to remap all skethces and external geometry (i did that and it took forever...). See https://wiki.freecadweb.org/Topological_naming_problem

Must trim a very very slight amount off of the center pin on keyswitches over the body/thumbcluster rod
- switch above this must be rotated to give clearance for the rod locker
-
Thumb cluster end of rod gets glued in place
