BB King is here to help!</p> <p>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!</p> <p>VIDEO: <a href="http://youtu.be/3pl6-AXtWZY">http://youtu.be/3pl6-AXtWZY</a></p> <p>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.</p> <p>I had to scale the model up a hair and that is reflected in my THING file. The STL files are original scale.</p> <p>ENJOY!</p> <h3>Print instructions</h3><h3>Category: Parts Summary</h3> <p>My new YouTube Channel: <a href="https://www.youtube.com/channel/UCnnw56J_TeOsF4M_F5pPPJQ">https://www.youtube.com/channel/UCnnw56J\_TeOsF4M\_F5pPPJQ</a></p> <p>Is friction giving you the blues?
