Simple box for SPDT switch. I designed it for the 3dpBurner2 3D printed laser cutter/engraver ( http://www.3dpburner.blogspot.com ), but it can be used for any other project.
Print on STL position without supports. I use on the main AC line and refilled the internal box with hot glue for isolating terminals.
It´s ready to be fixed by using M3 stuff, double side tape or hot glue (i use double side foamy tape).
See pictures for assembling.
