BB King - the 3D Printed Roller Bearing

Is friction giving you the blues? BB King is here to help!

This is a proof-of-concept print to evaluate using standard BB bullets as the rolly bits in a 3D printed bearing. I'll be using what I learned from this in some projects I have coming up!

I'm using 6 mm plastic BB bullets and I printed my prototype in ABS at .1 mm layer height, 10% in-fill and with 3 shells on my original Replicator.

I had to scale the model up a hair and that is reflected in my THING file. The STL files are original scale.

ENJOY!
