Description
This is probably my best fidget toy! I printed dozens of them because people wanted them.
Edit: Meanwhile I have a bunch of different fidget gear ring designs.
EDIT: I reuploaded these as 3mf with parts for easy coloring; changing color of only parts 3 and 4 requires only 4 color swaps, allowing manual filament swaps or reducing waste for pooping single nozzle filament changers. Parts: 1: sun gear — 2: planet gears inner part — 3: planet top 2 layers — 4: planet bottom 2 layers — 5 ring gear.
I also added a turn tool ans matching turn tool slots inside the ring, which makes it easier to break it loose , and to break it in with a power tool.
And I added a set with a slightly wider tolerance for those who have difficulties breaking the rings free or run smoothly.
It's a small, but satisfying fidget toy. You'll probably not want to wear it all the day due to it's size, but it's unobtrusive enough so you can still do a lot of things while wearing it. But while wearing it, you have a fidget thing right at hand for some quick fidgeting. (I'm wearing one as I type, and fidgeting with it when I'm thinking about what to type next.)
Also the little planet gears look like plus signs - for some positive influence :) and they look quite a bit mesmerizing when moving in perfect unison.
I uploaded 5 sizes, 14mm, 16mm, 18mm, 20mm and 22mm. If you need another size, ask in the comments and there's a good chance I'll make that.
Printing:
You might need to use a bit of force to break the gear loose at first, but after a bit of breaking in it is supposed to run quite smoothly.
If you can't get it free, try:
Happy fidgeting!
