tractyl-manuform-keyboard VS dactyl-manuform-tight-trackball

This keyboard is an attempt to make a best-of-both-worlds combination between the modular (and support-saving) design of dereknheiley's compactyl manuform (with adjustable wrist rest mounts) and the trackball-enabled design of the noahprince22's tracktyl manuform, forking the firmware from Schievel1's dactyl_manuform_r_track.

The tractyl manuform from noahprince22 outputs a model with a test hand with the finger length input from base to knuckle to knuckle to tip. I've found it gives a pretty decent first impression of the alignment of the dactyl in your hand. To get it just you do need some iterations with a test model

https://github.com/noahprince22/tractyl-manuform-keyboard this one does, its quite different from a lot of other manuforms, so it might be worth just using the code that generates the slots for the daily sockets and adding to a variant you like

Tractyl Manuform

So, I followed this guide to build my next keyboard. The only difference between mine and this one is that I added an encoder to the right side, and I used 2 Elite-c instead of 2 Pro Micro.

I wrote a build guide for mine here https://github.com/noahprince22/tractyl-manuform-keyboard. Basically just some ball bearings. It's less frictiony than the Logitech trackball I tested in best buy.

You can check out my zmk fork, the trackball works great (scroll to the firmware section): https://github.com/drorchen/dactyl-manuform-tight-trackball
