I've been 3D printing slinkies (helical coils) and I used build123d for it. Somebody on HN recommended it as a first pass if you don't know CAD.

It's a little rough but I was able to get it to do what I needed it to! Here's my code: https://github.com/freeqaz/light-coil-model

Let me know if you want one. They're pretty rad!



Can you do other shapes of slinkies, not just circles?


I've seen mass-produced ones in various shapes. For instance, stars. OP probably could, not especially complicated.

Notably worse at the act of 'slinking'. Would tangle like no other!


Yes haha exactly. I'm sure I could figure out the code to slinkify any object which would be pretty fun

For a non-circle that still works for slinky purposes, I'm sure some sort of geometric prism would be cool. Maybe I'll take a crack at it over winter break!
