There are two versions of Knob, the first one is in one piece and the second one is splited in 3 parts. They have to be glued together. Multipart knob is prepared for encoder LED backlight. The middle part should be printed from transparent filament, I suggest to use transparent PMMA.
Required parts:
8pcs Kailh 1350 - Low Profile Switch
1pc Arduino Pro Micro
1pc USB C Female connector on PCB
1pc micro USB male connector
1pc Rotary Encoder KY-040
5pcs 3mm heat set inserts (for back cover)
5pcs M3 x 8 mm flathead screws (for back cover)
2pcs 2,5 x 6mm screws (for encoder)
wires
Keycaps can be 3D printed, Stephan Park made them and he uploaded them on GrabCAD site: https://grabcad.com/library/kailh-lp-choc-pc-keycap-1
Optional parts - for LED RGB backlight:
12pcs W2812 2020 LEDs (1 for each key and 4 for the encoder)
1pc resistor 470Ω (between Arduino LED control pin and LED data/signal pin)
It was designed for tight fit, so your printer has to be calibrated, otherwise switches won't fit.
