Aurzen Projector Hanger

I have an Aurzen projector that I needed hung up, so as a first project using CAD I figured I'd model and print one :)

I'm no mechanical engineer so this is far from the perfect design but it's been hanging up and working for me for several months. It was also designed for a specific use case, being hung up by a protrusion from the ceiling. The design is simple, there is a bottom piece with a carriage bolt insert that bolts into the projector, a ball with an arm that lays in the spherical hole in the bottom piece, and a top piece that both bolts to the bottom piece and contains screw holes for locking the ball and socket joint once the desired projector position has been achieved. Lastly, there is a plate (use two of them) that holds the arm up and screws the entire assembly into the ceiling.

I printed this using CF-PETG for structural rigidity and slightly higher heat protection than PLA offers at 30% hexagon infill.
