As simple method to model wave washers https://youtu.be/j98QOT6z0sM [image: Screenshot 2025-02-17 at 10.03.27 PM.png]

That’s cool, but the code is a little hard to follow in the video. I did this for a drawing. It’s the half of the washer that is visible. When it’s almost fully compressed, as it would be when installed, the steps don’t show! `h=1; // half height (c to c)` `w=4; // width` `for (i=[0:180])` `rotate([0, h*sin(8*i), i])` `translate([-50, 0])` `ccube(w, 1, 1);`

Basic idea here is to draw a sinewave in x-z plane and draw a circular path to wrap the sinewave in x-y plane. The function which i wrote in python for such wrapping is "extrude_wave2path". Number of points in sinewave should match number of points of circular path. This weapped sinewave will make a path and then extrude a rectangular section through this path to create a wave washer.

your code is very nice, it is much faster and meets the intent On Wed, 19 Feb 2025 at 05:27, Caddiy via Discuss <discuss@lists.openscad.org> wrote: > That’s cool, but the code is a little hard to follow in the video. > > I did this for a drawing.
