First Look: Planetary Gear Fidget Spinner
The Planetary Gear Spinner from Real Gear Spinners has a prototype and it looks very interesting. The video above shows the maker giving a brief rundown on the design and giving it a few spins. These geared spinners have a lot of friction obviously created by the teeth of the gears fitting around the inner circumference of the outer circle, and are more engineering marvel than long spinners certainly. The Planetary Gear Spinner looks exceedingly intricate for even a gear spinner. It has the look of a Maelstrom without any of the simplicity.
