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.

Print - you may have to scale up the model if you don't use my THING file or you have a different size of BBs.
Load - Fit as many as you can leaving one out to fit the key in.
Lock - slide the key in to long the bearing tight.
