Summary

This ball and socket part is the same as the ones in this system:
https://www.thingiverse.com/thing:824711
except that it is two times the height. It was made to reduce the number of joints in a helping-hand setup, thereby providing added rigidity. It was also made to get things higher up without using as many parts.

I print it with the socket down on the bed and so it needs support. The raft also helps keep it from falling down. The large amount of infill is for strength.</p><p>Note that the OBJ and STL files were exported from Blender. Cura was able to open the OBJ file but not the STL. I assume this is a Blender issue.</p></div>
