This is a spring designed for 3d printing.
Watch the video to see it in action! http://www.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. www.Fablicator.com

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.
