Fidget Ring Spinner Planetary Gear

Here's an easy-to-print fun fidget ring spinner based on a planetary gearbox.

I wanted a smaller version of my popular YAPSR - Yet Another Planetary Spinner Ring and this is as small as I can get it! I spent ages optimising it for as much “spin” as possible! It spins really nicely :) 

I have uploaded a few versions and sizes.

• Standard all-in-one print - a single all-in-place print in PLA - there are 3 sizes

• A version which prints PLA for the ring but has an outer you print in TPU which gives a lovely feeling to the ring

• If you print just the ring, without the outer TPU you get a nice herringbone effect.

After printing add a little oil lubricant to the gears to make them spin nice and easily!
