Finger Spinner

This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/0WTOfneRpdu

This is an updated version of an earlier one i found on thingiverse. The shell was little small when i printed it before, so i made it 102% from the old one. Now my Rollerblade bearings pop into it very nicely. I also made the middle pieces bigger so there is less wiggle room between them and the spinner.
