Duplex Combo Switch Cover Protector Lock

thingiverse

I have 3 light switches that can cut power to my AC units. I didn't want people to be able to turn them off by mistake.I've seen a few designs that do this. I actually used [this one](https://www.thingiverse.com/thing:69806) on 2 of my switches, and it worked out awesome. However, on my third switch, that design won't work because my switch looks like [THIS](https://amzn.to/2U87XoG). I couldn't find anything else that was suitable, so I designed my own. This is literally the first thing that I've designed myself, so it's probably not the best or cleanest, but it definitely does the job. If I were to do it again, I would probably make the dome a little smaller, but I think it works out well. There's room enough to get your finger in there to turn it off when needed, but no one will turn it off by mistake. I used some [HatchBox White PLA](https://amzn.to/2ZejYyx) and did some quick sanding after printing and it actually looks pretty decent. Leave a comment if you have any questions.
