Fidget Spinner Bearings To Pennies

thingiverse

I've redesigned many fidget spinners using bearings as weights, but even low-cost bearings can cost around 50 cents. Many of us initially focused on designing with nuts, yet a significant number of designs still rely on bearings. I created a container that holds three pennies and fits snugly into the bearing slots, allowing for an affordable upgrade that brings the weight very close to optimal. These designs are specifically tailored for PLA shrinkage, but other materials may experience varying degrees of shrinkage, resulting in either too tight or too loose fittings.
