Case for Heat Bed Power Expansion Module

A compact case for a classic heat bed power expansion module. A series of holes allows air flow for the MOSFET. The cutouts for the cables are designed so that the case can be removed without unplugging the cables. The 4 screws for the cables can be accessed while the case is mounted. Included is also a spacer for the PCB that can also be used as a drilling template.
The holes for the mounting screws are 2.8mm in diameter for M3 screws, so no additional nuts are needed.
