Hypno Gear Fidget Spinner

Hypno Gear Fidget Spinner - Counter-Rotating Hypnotic Gear Spinner

No glue - fast print

A compact mechanical fidget spinner with a hypnotic twist.
This design uses an internal gear system to drive two discs in opposite directions, creating a mesmerizing visual effect while spinning.

The effect wheels are easy to swap, making it simple to experiment with different colors and visual effects.

The top layer features a flowing turbine pattern, while the underlying black/white disc enhances the motion with strong contrast. Together they produce a dynamic moiré-like effect that keeps changing as it spins.

The outer ring acts as both frame and grip, while the partially visible gear adds a subtle mechanical touch.

Designed for smooth rotation, satisfying interaction, and a clean layered look.
