To complete the upgrade of the Printrbot Metal Plus, the PC power supply was supposed to get replaced with something more appropriate, like a Mean Well LRS-350-12. After receiving the power supply the realization set in that all those 230V and 12V contacts need to get covered.
FreeCAD FTW! While designing the power supply cover I refined a technique to print one piece with multiple segments that can be folded into a final shape.
The FreeCAD design file and an STL can be found on github.
