Smaller Spinners

I decided to remix this object http://www.thingiverse.com/thing:1802260 to make it my own. Using a Community Shaper Generator > Circular Array I added a bunch of hollow cylinders to add grooves to the edges. I also moved the caps to be inside the spinner design to save filament with the raft.

This picture shows four spinners printed with a Brim build plate adhesion option. I wouldn't use that again with this design because peeling away the brim left sharp edges all around the spinners.
