Fidget spinner no bearings single print

thingiverse

This is an innovative fidget spinner that can be produced in one print without any bearings. It relies on a captive bushing to function as the bearing, maximizing spin time by placing mass at the edge. While not as effective as those with bearings, it offers significant cost savings, printing for approximately 50 cents in plastic for the larger version and 15 cents for the smaller model. By applying lubricant to the crevice around the hub, a substantial improvement is achieved, enabling spin times of up to six seconds. To further enhance performance, consider printing in nylon for an extra-smooth experience. Additionally, a custom SCAD file has been attached, allowing users to personalize their fidget spinner according to preference.
