Hundreds Maths Spinner Toy

Hi everyone,

This is my take on a maths spinner. I wasn't 100% happy with the designs I found online so I decided to design my own.

The rings are designed differently so that the feel of each click is the same in both directions and it I've tried to make the snaps into place firmer and with less wobble. I have also knurled the two end caps for added grip and shrunk the number rings in width so that the overall size is comfortable to reach.

Its still a work in progress but I thought I'd share what I've come up with so far so that maybe you guys could improve it.

I have a multimaterial printer so i've added coloured number inserts. In all honesty I found this difficult to print well so printing them seperately and gluing them in might be easier. Otherwise, just leave them out.

I hope you guys have more luck with it than I have so far.
If you have any suggestions please leave me a comment or if you can successfully print the rings in multicolour I would love to see i
