This is a bracket to mount a Raspberry Pi 2 case to the side of a Duplicator i3 Plus. It was designed with the dimensions of the Canakit case but should fit most Pi cases. The dimensions of the Canakit case are 62.7mm x 93.7mm x 31.4 mm and there is about 1 mm of tolerance in the actual bracket itself. Larger cases should fit. Smaller cases may require slight modification so the clips hold it in place.
On the right side of the Z axis gantry there are holes for mounting a z-axis limit switch, but they aren't used. Use M3 cap screws and nuts to attach the bracket and insert the case with the USB ports facing up.
