Making changes to qmk layout
Couldn't find the keyboard for me, so I made it.
Based on Sofle/Lily58, with Corne style key backlighting
Designed to use screws and locknuts to tent.

Questions
How big is the RGBCakeBoard PCB?
It measures 167.5 × 120 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RGBCakeBoard use?
106 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 RGBCakeBoard KiCad files?
From the DerekLamb/Rainbowcake repository on GitHub, at the commit this page was made from: the board is RainbowCake_kicad/RGBCakeBoard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the RGBCakeBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask DerekLamb before reusing the design.
