my suggestion is to use a skeleton-edition style case so you print the minimum amount needed, and reuse the base plate. ie print only thumb plate til you get the position close, etc.

I’ve build a framework for this approach: https://github.com/wolfwood/tryadactyl

trying to link the keyboard parameters to measurable features of your hand helps some, but honestly there’s no substitute for typing on it and realizing what you don’t like :)

i’ve has a recent breakthrough (implementing hierarchical/delegated column placement) that makes merging multiple plates with differing centers of rotation just work when switching from an open case style to a closed case.

Cut it up! Print only thumbs for a while that you can “locate” to a standard set of finger keywells. Do the same for other features you’re wanting to customize.

There’s a 3D hand model roaming around somewhere that you can put into the Dactyl model and give it a try. Also, if you know anyone with a Kinesis Advantage (2 or 360) you can test drive a default Dactyl (it’s based on that). I 3D printed mine blindly knowing that I have smaller than average hands and want more aggressive stagger + tent and it worked out really well for me.

Also check out Ergogen and Ergopad for truly customized to your hand experiences. This video is a great primer.

I know this is not part of your question, but I those wrist rests are beautiful. When you do get the layout you like, make the rest. Haha

This thing is gorgeous!

Any refs on those wrist/palm rests? I’m thinking to make myself some once I finish wiring mine up.
