For my garage door opener, the obstacle detection sensor some times gets hit by bright sunlight, and it will not close properly. In my mounting bracket, I noticed there is an unused bracket which looked like it would easily hold a custom cover. So I made one.

I'm including both a .step file and a F3D (Fusion 360) file, since I suspect my bracket is pretty specialized.

Feel free to edit to fit whatever custom mounting bracket you may have.
