Decora Light Switch Blocker - Complete Cover

thingiverse

Here's a cover to slip over a Decora style light switch. It snaps on using the existing switch plate screws. I had a 3-way switch circuit and it was frustrating that the upstairs and downstairs switches were always out of sync, so I just wanted to disable the upstairs switch - thus this cover. The screws are typically 6-32. You'll need longer screws to reach through this cover and into the threads. I think I used some 1/2" length screws I had on hand. As with all my designs, I've included the Fusion360 file so you can see how I made it or make your own modifications. Check out my other designs for other cool stuff for around the house.
