Parametric spinner in Fusion360

thingiverse

Parametric spinner in Fusion360 based on 2ROBOTGUY's designs. Autodesk link to latest version: http://a360.co/2q1n1o5. Go to Modify->Change Parameters to alter significant dimensions. As designed, sized to hold four quarters as weights (24.26 mm), resulting in the heaviest weight using US coins. Using a weight_od of 22 yields the standard four bearing spinner. Check [here](https://www.usmint.gov/learn/coin-and-medal-programs/coin-specifications) for additional coin sizes. With a 608 bearing, only as many coins can be held as will stack into 7mm. Four quarters turn out to be exactly 7mm. Due to edge fillets, best results are achieved by printing as two halves, then carefully aligning and gluing them together. Most slicers can split a model by dropping the model down through the bed by half the width (3.5mm). Also includes drawings for my threaded caps.
