Improved Bearing Tensioner

thingiverse

Mounting the experimental roller skate bearing onto both motor bolts requires a delicate touch to pinch the belt tightly against the gear with just a hint of flex in the plastic. The middle bearings, nestled beside one-armed clips, are my go-to choice due to their snug fit, though they can be quite tight. For added comfort, I opt for the topmost bearings, which offer a slightly more relaxed experience. Given their affordability, it's definitely worth printing both designs and putting them to the test to see which suits your needs best.
