This is my first spinner. I made it on Autodesk Inventor Professional 2017, and printed it withe Makerbot Replicator Mini+. You will need three 1/2" steel balls or marbles for weight on the outside, and obviously a bearing in the middle, having a diameter of 22mm. I did not make my own Ball Bearing caps, but you can find those easily on Thingiverse.
