The Monkey Spring is a 3D printable, durable parametric compressive spring that can be used just about anywhere. It is lightweight, durable, and parametric! You can size it for just about any application and control how strong it is just by changing a few variables in Monkey Spring.scad (you can even import it as a module and use it in your own OpenSCAD projects).

FEATURES:

• Extremely durable. Guaranteed to withstand at least, "a zillion cycles".
• Easy to print. No supports necessary!
• Completely waterproof (will never rust) and very strong chemical resistance.
• Two modes of operation: Can act as a linear spring or a buckling spring (similar to rubber dome).
• Does not weaken (significantly) over time!
• Useful for a broad array of applications.
• Can provide the equivalent to a spring steel spring in a smaller amount of space.
