Summary

This is a fun fidget snake. There is a little ratchet mechanism on the connecting wheel that allows the snake to keep its shape. These also give a pleasing 'chunkyness' to the motion as you move it in your hand.

I have included the basic files for each type of link, and pre-supported versions.
After printing, my supports snapped right off - and then I sanded down the little bumps with 800 grit wet sandpaper to get the result shown in the image. Your results may vary depending on the printer/resin/settings.

I printed out sets with 12 standard links and one of each end - bagged them - and gave away as gifts. Part of the fun is putting yours together. And you could mix/match colors.
