Chaos Pendulum Spinner v2

thingiverse

Spin a chaos pendulum wildly in your hand! Based on the roablade spinner: https://www.rotablade.com/pendulum-new/ Requires three 608 bearings and one 12mm metal ball for optimal performance. I believe that the 15mm ball is too heavy compared to the bearings, which compromises its functionality. However, it's what I had available, so I'll consider ordering some 10mm balls to rehash the design. You will need two of: Outside piece Outside Pin Handle And only one of: Inside piece Center Pin Some sanding is required for a smooth finish. Additionally, gluing or epoxying the outside pins to the outside parts helps ensure everything stays in place, while everything else should friction fit together seamlessly.
