PCB
Here you can find the KiCad files and Gerbers for the KLOR.
CASE
Here are the case files for the KLOR. There is an acrylic case and a 3D printed case (which uses acrylic too) for every layout.
SWITCHPLATE
In every case directory you'll find the matching switchplates as .dxf, .svg, .stl, and a .zip-file, containing gerber files for a FR4 plate.
KNOB
You can use pretty much any knob, which works with the EC11 encoder, but here you can find one, I designed for the KLOR.
BUILD GUIDE
Here you can find the build guides for the KLOR.

ZMK config (supports OLED, encoder, LEDs and Bluetooth)
KMK config (supports OLED, encoders, LEDs and speakers) made by Moritz John
Thanks to Manna Harbour you can find KLOR in Miryoku ZMK
CHOC/KS27 VERSION
Sadek Baroudi did an amazing job in creating a version of the KLOR which supports KS-27 and Choc V1 switches. Including a special case for it.

People who helped me create this board and fix stuff
If you build a KLOR I would be pretty happy to see some pictures. And if you want to leave me a tip you can do this here (but please don't feel pressured)

Questions
How big is the Klor1 3 PCB?
It measures 160.1 × 118.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Klor1 3 use?
84 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 Klor1 3 KiCad files?
From the mitTheos/KLOR repository on GitHub, at the commit this page was made from: the board is PCB/klor1_3/klor1_3.kicad_pcb and its schematic PCB/klor1_3/klor1_3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Klor1 3 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
