Multicopter hinge (square tubing)

This is my design for a hinge to be used on a multicopter arm to be used on any multicopter with a 14mm square tubing arm. It could easily be scaled to be used with other tubing diameters.

I'm sure it can have other uses as well.

I have not yet printed this but would probably use a high infill for strength.

You would need to print 2 of these for each hinge and it would enable the arms of a multicopter to be folded down for transport. My intention is to cut the arms close to the body a
