Features
- Custom 3D printed keycaps
- Choc v1 and v2 compatible hotswap
- Wireless dongle
- PCB generated in ergogen
Compatibility/Disclaimer
Everything in this repo has been tested. Even so, use these files at your own risk. If you decide to have the pcb fabbed, 1.2mm pcb thickness is recommended. Higher thicknesses are still compatible but add height to the case.
- Status of keycap compatibility: only keycaps that are <=17.85mm wide and <=18mm deep are supported
- Status of bottom case:
cutouts are currently only compatible with choc v2 with the exception of the lever keys, which have cutouts that support both choc v1 and v2fully compatible with both choc v1 and v2

Questions
How big is the Case bottom PCB?
It measures 254 × 125.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Case bottom use?
36 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Case bottom KiCad files?
From the dohn-joh/alias repository on GitHub, at the commit this page was made from: the board is ergogen/output/pcbs/case_bottom.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Case bottom design in my own project?
Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
