Plastic Coil Spring Model with Concentric Cylinders
Design preview. Rendered from the file, not a photo.
This model is not currently offered as a verified ready to buy print.
What it does
- Concentric cylinder shape restricts motion mostly to a vertical path
- Outer springy section adds a coil-like look around the cylinders
- Vertical bars and horizontal rings show a metamaterial spring pattern so you can see the design at work
- Shaped as a compression spring model for hands-on study of coil behavior
- A desk piece for anyone curious about spring mechanics and metamaterial design
Springs come in many forms. This one takes the shape of concentric cylinders, built to show how a coil spring works without any metal parts. A springy outer section wraps around the cylinders, giving it a look that mimics a traditional coil spring while working through plastic geometry alone.
The vertical bars along the cylinders guide movement mostly up and down, while the horizontal rings shape how far that movement can travel. You can see both ideas built right into the piece, making it a clear example of metamaterial design where the structure itself creates the behavior, not the material.
This piece works well on a shelf or desk for anyone who likes studying mechanical ideas or teaching spring concepts. It gives you a physical way to look at compression spring behavior up close, without needing a real metal spring on hand.

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 We have not load tested this design, so we do not publish a weight rating.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.
