China Beamer ceiling holder

I bought a Mentech projector from Amazon but couldn’t find a suitable ceiling mount, so I designed my own solution.

The projector slides in from the side and fits securely with minimal tolerances. Two screw holes are included for a reliable ceiling or wall mount. Alternatively, the holder can be attached using strong double-sided tape if drilling isn’t an option.
 

The slot dimensions are designed for a projector with a width of 104 mm and a thickness of 6.5 mm.
 

A friend tested the mount with a cheap projector from Temu, and it generally works as well. However, the small anti-rotation recess doesn’t fit perfectly on that model. If the projector isn’t moved, it still performs fine.
