3D-printable hand-strapped keyboard

Overview

Note: This repo has not been cleaned up and prepared for general consumption at all. This is just a dump of the project files. If there is any interest I will be happy to clean it up, put up some instructions on how to customize, print and build this keyboard. I'm not sure how useful that would be though. The keyboard has been adjusted to my hand and probably wouldn't serve well anyone else. So at this point it's basically a proof of concept.

What's this?

3D-printable parts of a pretty weird but fully functional keyboard. My design goals:

  • It has to be fully usable while walking, since I like to pace back-and-forth while thinking
  • Even though it's strapped to the arms, it should not hinder basic manual tasks that a programmer might need to perform during his work, most importantly: preparing and drinking coffee.
  • It should be impossible or extremely rare to 'get lost' on the keyboard, i.e., to become uncertain where specific keys are located in relation to the user's fingers
  • It has to offer all the keys, including modifiers, for normal writing, programming and using software such as vim, tmux, etc.
  • The typing speed should not suffer too much. It might be impossible to reach the same speed as on a standard QWERTY keyboards though - some sacrifice is acceptable
  • (Non-critical) It should look nerdy

Name and pronunciation

Viosuo is pronounced like the Polish word for oar. I chose this name because an early prototype looked a lot like an oar and was as uncomfortable as it sounds.

What's in this repo

  • The stl/ subdirectory contains STL files of the most recent design. All of them can be easily printed on Ender 3.
  • The viosuo.FCStd is a FreeCAD file with the entire design. It's done really, really badly mostly due to my inexperience, but also because I was working around the Topological Naming problem.
  • macros/hole_puncher.py is a simple FreeCAD macro that for a selectedy Body finds all surfaces that look like they might be inteded for a key and cuts out a 14x14mm square through the middle, intended for an MX switch
  • macros/fc_plumbing.py is my quickly-abandoned attempt at writing a framework that would make python scripting in FreeCAD much easier. I still think somethink like this would be an amazing tool and should be reasonably easy to create but I'm too lazy to do it myself. I'm including this here since hole_puncher depends on it.
  • zmk/ is my fork of the ZMK framework with a keymap and all the necessary boilerplate for Viosuo added.

Um... I don't know. I will pick one if there is any interest. It will be something open and permissive.
