Adjustable Coin Weighted Fidget Spinner

cults3d

The world has gone wild over Fidget Spinners, prompting a wave of requests that make it possible to adjust the weighting without needing to purchase a metal bearing - thanks to 3D printing technology. The Coin Fidget Spinner is an all-3D-printed Fidget Spinner with the ability to add weight using coins and/or washers for optimal spin performance... great fun experimenting with! One interesting thing is that too much weight can slow down spin acceleration, while too little weight reduces spin time due to insufficient momentum. Experiment with your spinner to find the perfect spin balance. Add weight using coins or washers up to 22mm in diameter. Applying a light lubricant (silicone or similar) to moving surfaces greatly improves spin speed and duration... just like a metal bearing on dry surfaces, where drag is created by two dry surfaces moving against each other - lubrication solves this issue. Separate .stl files are provided for the body, caps, and shims as follows: The body includes the 3D printed plastic bearing and body that holds weights (coins and shims/spacers). You can print just the body and it will still function well as a spinner. Caps (print 3) screw into the body to hold the weights and shims/spacers. You can also print just the body and caps (no weights/shims) for good spin performance. Shims/Spacers are provided in various thicknesses to ensure your 'weight stack' is tight and doesn't move around when spun, affecting balance, spin speed, and duration. The correct shim/spacer size should make the weighting stack slightly higher than the inner depth of the cap.
