Gyro Toy

A simple gyro fidget toy, similar but slightly different to the others :)

All the layers are concentric spheres with the same central point of rotation, which should mean it rotates freely in all directions if printed perfectly. I've made it as thick as possible to help the outer spheres turn nicely, but still have the central sphere print reliably.

Inspired by the keychain by Jangles1981 (https://www.thingiverse.com/thing:1871579)

It's a quick print - give it a go! Scale down to 50-80% to make it even quicker and for more of a challenge!

I've added a second file with more rings and slightly tighter tolerance. I've no idea why the file size is so much higher despite the only slight increase in complexity.
