This is a repo with the files used to make my own mechanical keyboard.
Why? It seemed like a fun project to do.
A journal of the time spent is available at report/report.pdf.
I used KiCad, and Fusion360 for this, and had to learn both of them. All images are in the report.

Questions
How big is the Keeb PCB?
It measures 466.6 × 138.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keeb use?
433 parts, built around the SK6812MINI-E. 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 Keeb KiCad files?
From the ShadowFox88/keyboard repository on GitHub, at the commit this page was made from: the board is pcb/keeb.kicad_pcb and its schematic keeb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keeb design in my own project?
Its repository states no licence, so its author keeps all rights: ask ShadowFox88 before reusing the design.
