Description
This is a spring designed for 3d printing.
Watch the video to see it in action!
youtube.com/watch?v=UxwbQSMbEIA
The more you scale the spring, the smaller the spring constant.
Increasing your filament width increases the spring constant.
The spring can be used in tension or compression, but it must be fairly short with comparatively thick filament width to be used in compression.
It can be made extremely flexible and it is very fun to play with.
It's form was discovered by accident, as it was originally auto generated support for the middle of a hollow cylinder.
I'm still perfecting the design but it works quite well in it's current state.
I will be uploading different sizes (and source files shortly) over the next few days.
The spring was prototyped on a Fablicator.

Instructions
Print completely hollow, no shells. Just turn fill OFF.
Adjusting your extruded width will alter the spring properties. Also, scaling the spring will alter it's properties.
Have fun.

Found it in a petri dish and were going to throw it out you say? :) Actually I'm occasionally surprised at how much people pass over my snazzy printed items to play with and dissassemble the scraps.

Nice spring, but I'm more interested in the printer you made it on.... how'd you come across one ;-)

If stretched does it pull to get back to it's shape or is it just flexible? Could it be used as a kinetic energy store in a wind up motor?
More from Landru
Printed it out with settings as stated, printed a solid bar basically..went to springymathing and it snapped into five pieces. Wooo. :( Don't know why your model has a large bar of solid space. Going to modify the .sldprt to represent your printed version.
