Summary

This is a 3 part print to hang speakers from the ceiling. You can rotate in 360 degrees and tilt depending on the size of the speaker.

I used this with fairly light speakers (about 2lbs/1kg), test the hold strength before hanging any heavy or expensive speakers on the ceiling!

Use epoxy to attach the base (body3 or body3_smaller) to the top of the speaker.
Insert body2 through body1 and screw body1 to the ceiling.
Then bolt body3 to body2.
Position and tighten the bolt!
