I heard you like springs (Flextest)

I heard you like springs (Flextest) 3d printed Gadgets Games
The Flextest contest made me think of springs. And as I like recursive stuff, I decided to make a spring out of a spring that's made of a spring. Three levels of springy.

The purpose of this item is to answer these fundamental questions:
- How long will it be when stretched? (my calculations say you might need something like a volleyball court to test this)
- Will it return to its original shape afterwards? Or will it turn into the phone cord from hell?

The model was made with POV-Ray (as you can see in one of the close ups, it's made of about 77000 spheres strung together). The final model in MeshLab has 750000 faces.
cm: 29.58 w x 5.28 d x 5.28 h
in: 11.646 w x 2.079 d x 2.079 h


No, I made it for a contest around a new rubber like material which isn't available anymore. I think the wire was too thin anyway.

Did you print it one for yourself ?

It's similar to an incandescent lamp filament, a coiled-coil, or a fluorescent lamp cathode, often a coiled-coiled-coil. That gives the dual advantages of saving space and concentrating the heat in a smaller area.
