Spiral fidget spinner

A Spiral Fidget Spinner Works Well with High-Quality 608 Bearings. It's worth noting that this spinner features a cavity within its rim, effectively positioning its center of mass at its core. As a spiral is inherently off-center, this design adjustment is crucial for balance. To fine-tune the parameters, it's essential to measure the new STL's center of mass; I employed node-stl for this purpose. To maximize weight and momentum, as well as ensure proper functioning of the balancing cavity, infill should be set at 100%. However, to add structural integrity to the spinner's core, a 30% infill rate is recommended for the central area.
