Fidget Spinner Inserts

A number of fidget spinners use the usual 608 bearing (22x7mm) as a weight to improve the spinner's ability. I wondered how well printing something with a bit of weight would work instead. This is the result of this work!The bearings I was using were about 11 grams, where as this model is just a touch over 3 grams, but it does seem to provide enough weight for the fidget spinners I have - having said that the extra weight of using bearings does work much better.Make sure you have good dry filament given the tight tolerances needed for this to fit! If you find it too loose for your particular model, try printing at 101% and then sanding down until you have a tight fit with your particular fidget spinner.
