Closed Lightswitch Cover

This is a simple, no-frills cover for a lightswitch which keeps the switch from being flipped without taking the cover off the wall. I use it to cover a switch that controls the outlet that my 3D printer is plugged into, so that I don't flip it by accident or on instinct and ruin a print partway through. It isn't pretty, but it isn't ugly, and it gets the job done. If your printer is half-decent at bridging (or even if it isn't), you shouldn't need any supports. Prints in about 2.5 hours on my stock Ender 3 at a quality of 0.28 mm.
