$1.20 Fidget Spinner

This takes a single 608ZZ skate bearing. The three pods are filled with 4/ea US dimes. This is an exercise in pausing the print and inserting the dimes. Figure out which layer you need to pause at, or just insert the dimes as the pods are visible. Coat the outside of the top dimes of each stack with enamel clearcote spray so the filament will stick better. Otherwise, use 8 layers on the top so that it will fill in any gaps. Now your spinner is weighted with $1.20 instead of bearings, which generally costs more.

NOTE: In the pictured spinner, I changed filaments twice during the print to get a nice pattern. Not necessary to make this spinner.
