The Magnetic gear spinner is optimized to showcase an ideal gear mechanism in the style of a fidget spinner. With its nearly frictionless design, only the ball bearing friction remains. Due to the arrangement of the four spinners, the cogging of the repelling magnets is canceled out. This gives you a great spinning experience
Material you need:
