Fidget Spinner Single print No bearing

myminifactory

This is a fidget spinner that can be printed in one single print with no bearings required. It works by relying on a captive bushing that acts as the bearing, putting maximum mass at the edge to boost spin time. Though not as effective as ones with bearings, it's a cost-effective option, costing about 50 cents in plastic for the large version and 15 cents for the small one. Applying lubricant to the crevice around the hub makes a significant difference, allowing spin times of up to six seconds. Printing in nylon is also suggested to make it even smoother. The scad file is attached, allowing customization to your preference.
