I designed this keyboard case for fun, after posting it on reddit it many people asked me to share the 3D files so here you go.

Let's call this a beta, it's not “production ready”, the switches don't fit very easily in the holes, I had to file them a little bit to make them fit.

I print it with PLA at 0.2 layer height, 0.4 nozzle, 25% infill, support ON

I don't suggest PETG, it might come out not stiff enough

To build this keyboard you will need:

• 2 Arduino pro micros
• 56 ks-27 or kailh choc switches 
• 58 diodes 
• 2 of the shortest EC11 style encoder you can find (I used "HOY21406")
• 2 SSD1306 oled displays
• 2 2.5mm TRRS jacks (I used PJ218A but you might be able to fit slightly bigger ones)
• 1 usb c (usb 2.0) breakout board not bigger than 12x15mm (this ones fit perfectly)
• 1 sacrificial usb micro-b cable (unfortunately the main pro micro needs to be connected trough the usb port, there's no other way)
• 16 m2.5x4x3.5 brass knurls
• 16 m2.5x5 screws
• a hot glue gun and a good soldering iron
• at least 4 hours of time

You will need to use some hot glue to fix the display, the trrs jack and the usb c connector, if you want later to remove those parts from the board you can simply warm up the glue with a hot air gun and it will be free
