Summary

Ortho-planar springs are springs that can undergo a large displacement ineither directionwithout (much) rotation. They've got all sorts of practicalapplications.

This .scad (library with ortho_planar_spiral_spring() module) will generatea flat, ortho-planar spiral spring of whatever size and shape you want. Ittakes a number of options and there's a bunch of examples in the file so itshould be pretty easy to figure out.

I recommend inspecting your springs layer by layer in your slicer beforeprinting because it's real easy to make springs that have walls that are toothin for your 3D printer.

I've found that PETG works great for this style of spring if you don't need itto last more than ~200 cycles or so. If you want it to last I recommendusing something with a more robust fatigue index like Nylon or PCTPE(which I've tested and works great--even though it's not as "springy" asPETG).
