Summary

This is a simple Case to protect the electronics of a Power Supply module of those intended to be plugged into a breadboard or protoboard. It was designed for a particular model BUT bear in mind that there are many implementations of these power modules. I include a photo of the model I based my design on.
I am also providing the SketchUp 2021 source file (scaled 100:1) in case you would like to modify this design. To avoid large supports I broke the case in 3 pieces: a bottom piece and 2 cover or top pieces. These two top pieces can be glued together if desired to make the top piece a unique one, but you can leave them as a pair. The source file also includes a model of the Power module.
Other than the filament you will need 2 screws 2mm x 10mm and another 2mm x 6mm.
