The Planetary Gear Linkage Fidget Spinner is a CNC one-piece aerospace aluminum frame EDC spinner with solid brass gears, anodized sandblast finish, and a silent precision bearing — 83mm diameter, 30.5mm height, 156g. Available in six variants including Ferris Wheel 4-Gear and 9-Gear Linkage configurations. Free engraving up to 3 characters on the center hub. From $55.99.
Designed for engineering enthusiasts and premium EDC collectors who want a spinner where the gears actually move — a planetary gear linkage system that is as satisfying to watch as it is to spin.
About This Item
- Planetary gear linkage — gears that actually move. Unlike decorative gear designs, the planetary gear linkage on this spinner actually moves during spin — the brass gears rotate in a synchronized planetary pattern as the spinner spins. A kinetic engineering display in EDC form.
- CNC one-piece aerospace aluminum frame. The frame is CNC-machined from a single piece of aerospace aluminum — no joints, no assembly. The one-piece construction ensures dimensional accuracy and structural integrity.
- Solid brass gears. The planetary gears are solid brass — a premium material that adds weight, warmth, and visual contrast to the aluminum frame. Brass gears develop a natural patina with handling.
- Six variants — Ferris Wheel and 9-Gear Linkage configurations. Ferris Wheel 4-Gear (Camo and Black) for a symmetrical, wheel-like gear arrangement. 9-Gear Linkage (Youth Edition, Cool Black, Champagne Silver) for a more complex, multi-gear planetary system. Variant F for a distinct configuration.
- Free custom engraving (up to 3 characters). Initials or short codes engraved on the center hub.
Free Personalization Included
Character Limit: 3 characters
