Double Pendulum Fidget Spinner

thingiverse

I designed this double pendulum fidget spinner to be easily held and played with in one hand. My goal was to make it accessible for comfortable use. This design is based on my previous double pendulum spinner, but I shortened it by 10 mm to enhance its spinning performance in the hand. As a double pendulum, it exhibits chaotic motions regardless of how you move it. I utilized 1x 608 bearing and 2x 624 bearings for this model. For optimal results, pair it with full ceramic bearings or thoroughly cleaned steel bearings.
