Fully 3D printed projector mount! Not really a fan of having to use rubber bands or nuts. Tried to follow the original design. Took a couple of tries to get it just right. Should fit the projector and be a bit loose. Unless you are planning to use it upside down, it will hold the projector alright.

Printed it with the screw hole facing upwards to be sure there would be no supports inside it. The overall shape is pretty simple, so it should be a simple print. Could probably use 0.2mm.
