$1 Spinner

I took Luwe's spinner, which is my absolute favorite, and resized the outer holes to fit a US Nickel. Not only is a stack of 3 nickels slightly heavier than a 608 bearing, it's also a lot cheaper.

I call this the $1 spinner, because that's how much it costs me to make. 45 cents in weights, 50 cents for a 608 bearing and 5 cents worth of PLA.
