I have completed the design and it is ready to prototype. I ordered a ball from Custom 3D Stuff.
If you think all this stuff I did below is over kill: Well this type of design is what I do everyday.

I added an aluminum round standoff into the middle to act as a shaft.

I have created a Google Drive folder that has all the 3D STL and STEP files,. There is also an exploded diagram along with all the rest of the project files. There is also a BOM here for anyone wanting to get all the hardware. It costs $100 for the ball, thread adapter and related hardware.
I am going to prototype the 3D printed parts on a FDM machine and laser cut the flat parts. I will probably order final parts from Shapeways.




How about some fun image matched GIFs!
