Parameterized Screw Thread and/or Spring

thingiverse

My first ever Thingiverse upload! This is a screw thread described in OpenSCAD, and as a bonus you can use the helix module portion to generate a spring as well! I was trying to use the twist function in OpenSCAD, but a friend of mine mentioned using two rotated split toruses and this is the result. I've managed to print this out successfully, and this is part of a clamp I'm designing, but I figured this might be useful to someone out there. I have yet to try out just printing the spring portion, but it might work! Instructions The module takes in 4 arguments: d1: Diameter of the coil that makes the helix d2: Diameter of the main helix (add d1 to this value and it'll be the width of the whole thing from thread edge to edge) h1: Height between two coils. If set to 0, this means the coils are touching h2: Height of the whole helix/screw thread All inputs are in mm, and you can optionally comment out the last line to use this file as an included module.
