BB ammo Thrust Bearing

thingiverse

This versatile bearing leverages everyday BB gun ammunition as the functional bearings themselves. Simply print out two bearing halves, meticulously lay in place the tiny balls along their tracks, and carefully press them together to form a tight seal. Measuring an impressive inner diameter of 10 mm and a spacious outer circumference of 30 mm, this innovative bearing effectively streamlines motion and alleviates friction with effortless ease. By incorporating these bearings into my trusty windmill design, I was astounded by the notable reduction in mechanical resistance after making the switch from standard 608zz set-ups, thus catapulting efficiency to new heights.
