Planck Style Ortholinear 4x12 Keyboard

I made my own 4x12 ortholinear keyboard alternative to a planck for cost. The plate is reinforced enough that you could probably hand wire it but I had a PCB made for it.

Notes:

Print the plate upside down and the case bottom with supports. Supports are for the nuts and cable cutouts.

Use 5 m2 nuts with 5 12mm m2 bolts. If you screw them in without the plate/pcb it will pull the nuts into their sockets and they won't move.

The PCB is the Contra - https://github.com/ai03-2725/Contra which uses a pro micro which costs less than $5/pcb when ordered from somewhere like JLCPCB (min order 5). This is 231 mm X 76.2 mm and I left about 1mm padding between this and the case.

So total cost was about $65 with switches and caps making it pretty cheap in comparison to buying a premade planck and there are still 4 pcbs left over.
