About this 3D model

Needed a very special pivot for a creation I am working on. Came up with this design and thought to myself that it might be useful to somebody else also. I'll probably be using it in a couple other designs down the road. Also has a socket to connect more than one together. Here is a preview of the inside so you know how to assemble it. https://www.youtube.com/watch?v=-RqFT_3apMI Here it is in action. https://www.youtube.com/watch?v=d389U5de0EA
