Mostly Printable Ball Bearing - .25

thingiverse

The design features non-printed 6mm balls as rolling elements, which can be purchased as Airsoft BBs at sporting goods stores. This draft lacks a race; if needed, I will create one upon request. The STL files are available in both ASCII and binary formats. Ensure that the models are scaled with 1 unit equaling 1 meter; you may need to scale them up for printing purposes. Print two of each part and assemble by placing an inner and outer half on a table, aligning rods, followed by inserting nine balls into the gap between parts. Finally, place the opposing bearing parts and report back on the results.
