Adjustable Coin Weighted Fidget Spinner

thingiverse

The world has gone wild over Fidget Spinners so, due to numerous requests, this allows for the adjustment of weight to be made... no need to purchase a metal bearing as it's all 3D printed. The Coin Fidget Spinner is an all 3D printed Fidget Spinner with the ability to add weight using coins and/or washers to achieve the best possible spin... fun to experiment with! It's interesting that too much weight can slow down the spin acceleration but too little weight reduces the spin time because there isn't enough weight to maintain momentum. Experiment with your spinner to find the ideal spin. Add weight using coins or washers up to 22mm in diameter. It's also very important to apply a light lubricant, such as silicone, to the moving surfaces as this will greatly improve the spin speed and duration... just like a metal bearing on dry surfaces creates a lot of drag, lubrication fixes this. 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 the weights (coins and shims / spacers). You can print just the body and it will still function well as a spinner. The caps (print 3) screw into the body and hold the weights and shims / spacers. You can print just the body and caps (no weights / shims) and it will spin well. Shims / Spacers are provided in a range of thicknesses to ensure your 'weight stack' is tight and won't move around when spun. Any movement in the weights will affect balance, spin speed, and duration. The correct shim / spacer to use is the size that will make the weighting stack fractionally higher than the inner depth of the cap. Please refer to the print settings and images for additional information... and post images of your Coin (Weighted) Fidget Spinners in action for other members to see!

However, I live outside the USA so tips cannot be sent to me via PayPal.Me as that service is not supported in my region and this is beyond Thingverse's control.
