Fidget Gear Keyring - Easy assembly

Summary

This is a remix of the Fidget Gear Keyring Mini by Evaken. I liked the idea, but didn't like the assembly and the need of nuts and bolts.

So I reduced the number of printed parts and eleminated all hardware. Just snap the gears on the axis and you are ready to go :)

**UPDATE** 09/17/2021

added 6.4 and 6.2 gears upon request

I still recommend 6.6 gears since they are working for years now!

*UPDATE 06/26/2017

added new files:

1. body_rounded_new.stl - which provides a better feel while fidgeting. sharp edges were substituted by rounded edges.
2. body_rounded_web_new.stl - same as above, but with my web address
3. gear2_6_6_c.stl - all corners have been chamfered for better haptics, inner diameter is 6.6 which worked best for me on the UM²

Please don't forget to show a photo of your make / color combination :)

gear1 is a tighter fit than gear2. Both worked well on my UMO.
Start with gear1_6.8mm (which means 6.8mm hole diameter).
Let me know if you need other diameters.

Notes:                     

print the body with 66% and the gears with 22% — why 66 and 22? because it's faster to type in 66 instead of 60 ;-)
