Duplex Combo Switch Cover Protector Lock

thingiverse

I've installed three light switches that control my AC units, but I didn't want anyone to accidentally turn them off. I'd seen designs online that prevented this, so I used one on two of my switches and it worked out great. However, the third switch had a different design, which wouldn't work with its unique shape. After searching, I couldn't find anything suitable, so I designed my own solution. This is the first thing I've ever designed myself, so it's probably not perfect or elegant, but it gets the job done. If I were to do it again, I'd make the dome a bit smaller, but for now, it works well. There's still room to turn it off when needed, but it's safe from accidental turns. I used HatchBox White PLA to print it and did some quick sanding afterwards, which made it look pretty good. If you have any questions or concerns, feel free to leave a comment!
