The design is based on the excellent Dactyl keyboard, generated with https://ryanis.cool/cosmos/ and it runs the excellent qmk firmware. It is handwired:
and I have also made a palm support using inkscape and openscad
All printed on a reprap prusa i3 derivative.

Tried ball transfer units?
I've found Ruby balls ok sometimes but BTUs are where it's at. Expensive though.
