What it does

- Print-in-place. No assembly. No glue.
- Two tail options: pointed for the original, rounded for kids.
- 19 g of PLA. Lightweight desk fidget.

A slug with a fully articulated body. Each segment connects to the next with a snap-fit pivot. Print it, peel it off the build plate, and it wiggles.
The trick is the pivot tolerance. Tight enough the segments hold a curve. Loose enough they do not bind. 8ran's design hits the sweet spot. A rounded-tail option ships alongside the original for younger kids.

What it is made of
Designs like this print well in PLA. Compare the materials.
Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
