Prints as one complete piece—no assembly required
Concentric cylinders guide smooth vertical compression
Adjust stiffness & travel by tweaking bars and rings in the file
Twist-resistant design perfect for experimenting with metamaterials
Springy outer shell bounces back after every squeeze

This single-piece plastic spring is a clever 3D printed toy that brings mechanical experiments to life. Inspired by metamaterial design, it features concentric cylinders that guide movement vertically while an outer springy structure provides bounce and resilience. Whether you're tinkering on Thingiverse, MakerWorld, or Printables, this 3D print file is a fun way to explore how geometry creates function.

The design lets you tune performance: more vertical bars make it stiffer, while additional horizontal rings increase how far it compresses. It handles squeezing and compression like a champ, resists twisting, but isn't meant for pulling or tension. You can even embed the spring layer between cylinders to protect it from wear.

Perfect for makers who love functional toys, physics demos, or just satisfying desk fidgets. Print it, squish it, and see engineering in action.
