Light Switch Plate Blank Cover

Here's a bit of a niche model, hopefully it helps someone else. This is a project i made for my brother-in-law who has a 3-gang box in his house but only has two switches in it, so he needed something to cover the third hole in the switchplate. Ok fine, it annoyed me and I needed to cover the third hole in the switchplate. This is a designed with a tapered hex for a standard 6-32 nut in the back. You can tap it in or put a screw with a washer on the outside and turn it in until it sets, then they won't fall out the back. Then just put it in your cover plates with standard switch screws to cover the hole.
