Double Gears Spinner

A friend once gave me a used bearing from a washing machine, and I started wondering what I could make with it. Well — here's what I came up with! This fidget toy features two large gears connected by a central bearing, along with eight smaller "child" gears linked together. When you spin one of the small gears, the others all rotate in sync—super satisfying to watch in action!Printing & Assembly Notes:The print file includes a bearing model, but I recommend using a real 6202Z metal bearing for smoother and more precise rotation.You can print small gears in different bright colors by changing filament and putting them on separate plates, based on color.When assembling, be gentle with the small gears. The axles are thin and can break if forced.Leave a 1–2mm gap between the main and bottom gears by letting the bearing slightly protrude from the bottom of the main gear.Use a bit of glue to firmly secure the bearing to the bottom gear and prevent wobble during use.I hope you wi
