Small Adjustable Wall Mount with Ball Joint

Adjustable in several ways, this is a small wall-mount apparatus for light objects. It's based on the very nice Adjustable Ball Mount for Wall by smurf3d. In my case it holds a lightweight acrylic mirror at about a 90 degree angle from a wood shelf but can be adjusted quite a bit. I attached one end to the back of the mirror with double-stick tape, and screwed in the other end into a shelf.

Update 9/19/22: I placed the screw holes farther from the base so that it's easier to screw in place without bumping into the threads.

Print one arm, two bases, and two threaded nuts.

I made this in Tinkercad, and you can edit it there, free and online, to your heart's content: https://www.tinkercad.com/things/aLwCQ2ezp2t
