Hi! I made this little case for my Rpi zero2w. It was my first little project in Onshape.
The fitment is kind of tight for the fan and front grille but it all should snap together without the need for hardware but you will need 4 M2 bolts to mount the rpi to the case.
I printed mine out of PLA with a 20% infill. supports are strongly recommended for the case body.
I powered my fan by just soldering the fan leads to the rpi I/O.
