The Corne keyboard is a split keyboard with 3x6 column staggered keys and 3 thumb keys, based on Helix. Crkbd stands for Corne Keyboard.
This fork altered the footprints of the Corne Classic to support Cherry MX Low Profile switches.
For more information on how to build one see here
Despite the MX style stem of the switches these are not compatible with every MX style keycap. I included some more information in the build guide.
The switches route the light of the RGB LEDs quite nicely imo: https://imgur.com/7JVrjXo
I designed the footprint for the MXLP switch based on my measurements. The footprint file is included with the PCB. The switch has a tight fit.
