I designed this light switch cover because I had a switch with a hole to fit 2 switch in it and needed to cover the remaining hole;

-It sould fit most U.S style light switch covers.

-It will fit the standard screws to install the switch cover ( I used m3 screws in the photos because there is no metal box behind it to screw into).

After testing the first version (the left cover in the photo under), the holes didn't align correctly. To fix this, I made the screw holes as ''sliders'' (middle cover in the photo under). Finally I did a third version (right cover in the photo under), in which, I remade it but cleaner.
