Spinning Top and Roller Kit

Hi, I have added a CD hub to my 3d printing STL thingiverse download files.  Besides anything else you can do with it, the hub turns an old CD into a spinning top or rolling thing.  Here is the video showing the spinning top and a roller. 

The background for this design was working on clocks incorporating a CD to mount the face numbers. I am still working on that, but this design occurred to me along the way.
