Planetary Gear Fidget Toy

This 3D-printed planetary gear fidget spinner offers a unique and satisfying way to keep your hands busy. Unlike traditional fidget toys, this design features a smooth, donut-like shape with rounded edges, making it more comfortable to hold and spin. The built-in planetary gear system ensures a smooth, tactile experience, where you can feel the gears interacting as you twist and turn it.

What sets this spinner apart is that it comes out of the printer fully assembled (print in place) – no need for extra parts or assembly. The herringbone gears create an engaging and relaxing spinning motion, and since there’s no need for a cage to hold parts in place, the gears stay perfectly aligned.
