Skyrim "Dwemer" style Fidget Spinner - metal R188

Skyrim Dwemer themed Fidget spinner using R188 bearings.  It uses 12mm balls, Due to the weight of the metal body, balls can be things such as gem spheres, glass marbles etc.

Assembly:

1) Test balls and bearing pressfit into body, see number 2.

2) 3D printing is great but size may vary slightly.  Because of this sometimes bearings/balls may be a little too tight.  If this happens use "dremel" rotary tool in a circle in holes will usually open up enough.  Do a LITTLE at a time and try, too much and things will be too loose. 

3) Press in balls. Put a few drops of cyanoacrylate (super glue) on the BALL and let it drip into socket.  After dry scrape any excess glue from ball.

4) Insert 1/2" x 1/16" thk O-ring into groove, press in bearing.  If the spinner wobbles press in more in the high areas until straight. (If you used greased and/or rubber sealed bearings it will not spin long.  Remove seals and de-grease for best results.)
