About this 3D model
This is a case I designed for a Raspberry Pi 4B, with a Kali Linux logo on the top for a small vent.The only supports you might need are for the counter sunk holes for the machines screws in the bottom of the case.This case is assembled with four 10mm M3 screws in the bottom.I have printed mine in red PETG and .2 mm layer height, and it fits perfectly, with very little tolerance.You will want to have a well calibrated printer to make sure this prints correctly and fits correctly.Print time for my Prusa i3 MK2.5 was around 3.5 hours in total.
