Duplex Combo Switch Guard

thingiverse

This is a cover plate/light switch guard for a duplex combo switch-outlet. I recently installed a smart bulb in the entry hall, and didn't want people turning off the switch to it. This prevents someone from unintentionally flipping the switch, but still allows it to be used if needed. I printed this wall-side down, with supports touching the build plate (the back is hollowed out to let the switch fit flush.
