Parametric spinner in Fusion360 based on 2ROBOTGUY's drawings. Autodesk link to latest version: http://a360.co/2q1n1o5.

Go to Modify->Change Parameters to change relevant dimensions. As presented, sized to hold four quarters as weights (24.26 mm), as that gives the heaviest weight using US coins. Using a weight_od of 22 gives the usual four bearing spinner. See here for other coin sizes. With a 608 bearing, you can only hold as many coins as will stack into 7mm. 4 quarters turns out to be exactly 7mm.

Because of the edge fillets, best results are obtained by printing as two halves, then carefully aligning and gluing them. Most slicers can split a model by dropping the model down through the bed by half the width (3.5mm).

Also contains drawings for my threaded caps.

Printed it out and it worked fine. I had to do some sanding to get the bearing in. But that was fine.

The bearings are sized at exactly 22mm. That generally makes for a very tight fit. I have tried it with various amounts of clearance, but decided I prefer a force fit over having it become too loose after taking it apart several times.
