Printed Fidget Spinner Experiment

thingiverse

Experiment in making a fidget spinner without bearings. Printed with 100% infill and a few drops of oil in the pivot joints, it should spin for 15-20 seconds easily, but I haven't gotten it to last more than 30 seconds. It might do better with a heavier filament. It turns out that this design can be disassembled fairly easily, so there wasn't really a good reason to print it as a single piece. Taking it apart is the easiest way to oil the pivot points. I used the 0.05mm gap version but also included other gap distances. The pivot should stick slightly when it comes off the printer, but it should separate easily when spun. If you notice any wobbling, it's too loose and you may need to use a smaller gap or overextrude a bit. I used Atomic Filament Dark Cherry Red PLA, Translucent Orange PLA, and Fillamentum Blue PLA.
