This is a 15 degree bracket/frame used to hang my universal projector mount from my ceiling.

Please note that there is one superior printing direction! See images.

When printed on its side, no supports are needed, and the layers will be perpendicular to the stresses. I used 100% infill via perimeters/layers for maximal strength.

This design is quite strong and can very easily hold more weight than the ceiling drywall could before breaking.
