This is a fix/remix of TenDutch's Batman Spinner found here: http://www.thingiverse.com/thing:1845518
I found the original tricky to print with ABS due to the slight overhangs and uneveness of the design as well as the bearing inserts being too small and cracking the frame.
The original is now fixed to allow for a tight bearing fit but not enough to crack.
I also added a flat version that is much easier to print with ABS.

Note: This takes a standard 608 bearing. If you find the bearings too loose, print at 99% scale as suggested by donaldkwong.
If you find the edges warping a bit, then add a brim with .4 - .5 offset from the part. That should hold it down with easy cleanup.
