Had a 3 gang switch plate that only had 1 remaining switch (dimmer) in use. It was that way when I moved into the house. Instead of buying a new 3 gang plate with just 1 switch hole and the rest solid to clean it up, I decided to keep the plate and design a blank that would secure the plate and fill the empty switch hole. I made a few versions and the one I like the most is the thin solid version. Needs minimal support and only 7 grams of filament to print. It holds perfect to the box and gives great support to the plate using standard screws. Feel free to try the others if you like. Looks a lot better than empty holes in the plate. I printed mine white since my plate was white. Not sure if they have almond filament. Didn't see any other models out there like this and decided to share for anyone else needing a quick solution to a remodel/rewired switch box. Let me know what you think and if you print any please share how it fit your application. Enjoy and happy printing.
Note: The green wire tied to the screw made me laugh to see it that way on the box when I took the cover off. So I kept it in the same location after install to take the pic. I've since put it where it belongs.
