My roommate salvaged an occupied/unoccupied sign that was about to be thrown away. It would be a shame to throw it away though, so we intended to make it into an indicator of the occupancy of our bathroom. I made that work partly because of this motor mount.
The motor mount has a simple flat surface so it can be glued to any surface. You can also drill holes to mount it with screws too I guess.
The .step file for the design is also included, so feel free to tweak the part to your needs. Enjoy!
