Switch Cover

thingiverse

This is a simple cover that screws over a standard North American light switch to help prevent accidentally turning the switch off or on. Unless the screws are very short, replacement screws shouldn't be necessary - just unscrew the screws holding the cover plate in place and screw the cover in with the plate. If printing this on an FDM (filament printer) rotate the model so the large flat side is against the bed. This will improve strength by making the individual layers larger.
