Spherical joint proof of concept

This is a proof of concept for a spherical joint I've been developing. It is designed to be printed as one solid part without supports on the flat surface, then must be rotated to break the hinge free (it's quite easy as it was designed with a very weak base to the internal sphere for this purpose). The joint is quite strong and has a good range of motion and full 360° rotation. I intend on using this for future projects and would appreciate feedback on this model and ideas on possible applications. Also please feel free to try and break the hinge; I would like to find weak points and also receive feedback on durability. Thanks much!
