Here you'll find case, plate, and midpiece files for the Uni. Look in the stl folder if you want files to 3d print. I will explain what each file is below.
This is still a work in progress, plate and backplate is still missing.
Case is the thing you attach below the main PCB using stand-offs. It is very short, sitting flush to the top of the main PCB. Use this if you are not using a plate, backplate, or midpiece.
If you have a backplate and you just want to cover the space between the board and the backplate, the midpiece is perfect for you. If you have a v3, use the usbc version. If you have the v2, use the promicro version.
It's an experimental work that is only compatible with the v3 if you are willing to desolder the switches and then resolder them.
