I would like to share my keyboard built. It is mechanical ergonomic keyboard.
It was inspired by a dactyl keyboard (https://github.com/adereth/dactyl-keyboard) and Mitosis keyboard (https://www.reddit.com/r/MechanicalKeyboards/comments/66588f/wireless_split_qmk_mitosis/).
I wanted to print my dactyl keyboard. But I was not able to make it right sized for me. I decided to create more flexible keyboard first.
Any key can be set on different height holder. Holders can be set in a row. And rows are bind together by screws. This allows almost infinite flexibility of created keyboard.
The key holder has a ball joint allowing to angle it freely.
