Printed Fidget Spinner Experiment

cults3d

Experiment in creating a fidget spinner without bearings. Printed in 100% infill with a few drops of oil added to the pivot joints, it spins for 15-20 seconds fairly easily, but I've only managed to get it up to 30 seconds so far. It might perform better with a heavier filament material. It turns out that this design can be disassembled relatively easily, which means there wasn't really a good reason to design it as a single printed piece. Taking it apart is the simplest way to oil the pivot points. I used the 0.05mm gap version, but I also included a couple of other gap distances in the design. The pivot should be slightly stuck when it comes off the printer, but it should separate easily when spun. If you notice any wobbling, it's probably too loose and you may need to use a smaller gap or overextrude a bit. I printed this fidget spinner using Atomic Filament Dark Cherry Red PLA, Translucent Orange PLA, and Fillamentum Blue PLA filament materials.
