Description

Started this design back when there were no proper cases for the newer GM328A USB-C version here or anywhere else.

Uploaded it here along with the FreeCAD source in case anybody else needs it.

Printing and Assembly

Can be printed pretty much without supports using 15-20% infill. Assembly requires four M3x14mm flat-head screws and a bit of foam tape to pad the inner part going against the screen to keep it pressed against the PCB.
