Raspberry Pi CM4 IO Board Case

This is a case for the Raspberry Pi Compute Module 4 IO Board. I designed it to be easily 3D printable. The one part that needs support is the overhang by the USB ports. Just paint on some tree supports. My supports came off super easily.

3 walls should be used, as the minimum wall thickness in this design is 1.2mm.

I used 4 heat inserts that are 6mm tall and 5mm OD. The STEP file has parameters that allow you to easily adjust the height of the insert and the OD. It also contains parameters that change how far out the snap fit juts out and a printer tolerance parameter. You might need to change these if the lids don't fit together perfectly or the snap isn't holding the way you want it to.

Materials

4 M2.5 heat inserts of your choosing

4 M2.5 screws (6mm to 8mm)

I used M3, but it required me to widen the mounting holes on the IO Board with a drill. Don't do this, I was stupid for doing it, but I got lucky…
