3D Printed Gear Bearing Fidget Toy

Description

Need something quiet and subtle to do with your hands to help you focus? Fidget toys of any variety are the way to go.
This gear bearing fidget toy is a well-loved office favorite without the typical three-lobe design, so it's more comfortable in smaller hands and provides an intuitive and satisfying movement, even for first-time fidgeters. While the gears create smooth movement, the movement time is shorter than with metal bearings, requiring more user interaction—which is the whole point of having a fidget toy.
It's made with helical herringbone gears between an inner and outer housing, a design only achievable through 3D printing. The inner housing has a hexagonal hole through it, if you want to add an axle.
Diameter: 2" (51mm)
Thickness: 9/16" (15mm)
Color will be a grab bag of whatever color I need to use up first, or whatever's already loaded in my 3D printer.  If you want a specific color, please message me.
NOTE: These are most likely school-safe, unlike the popular triangular ones. Enjoy your fidgeting :)
