I needed a light switch cover to keep the outside motion-sensor triggered lights powered without rewiring. I also wanted to be able to leave one side open for when you really do want to adjust the switch.

I found this one on the site: http://www.thingiverse.com/thing:6688

I made it and it worked, but it's too thin on one side and I wanted to print it on glow-in-the-dark PLA so I could see switches when the lights were off & it didn't print well on PLA.

SO, I started from scratch and made my first Fusion 360 project. I've shared the STL and what I think are all of the Fusion files you'll need to recreate it. It turned out great - much more solid and it glows well.

For stability, I printed it with 100% infill, but it's probably not necessary.

Note: I printed this flat side down (not sure why the Thing Viewer rotated it)
