fidget gear ring - diamond knurling

This is a variant of my best fidget toy with diamond knurling, for those who like some more aggressive texture. 
Also see my other fidget rings (including a bracelet - because size does matter :)

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.

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.

I also printed these in dual color. I added one or two additional rings and set them to “flush into object” to convert purge poop into some strangely colored bonus rings - see image. I also reduced the flush volumes to 99 mm³, but next time I'll reduce that further.

Some tips if it doesn't turn:

• Some filaments seem to handle this better than others; silk for example seems to be prone to ooze and fuse. I used basic and matte.
• Also you can try reducing the flow ratio a few percent.
• Adjusting the XY size compensation is a third option to try (e.g. 0.02 for hole, -0.02 for contour).
