About this print
An OpenSCAD library for generating parametric threaded parts, including screws, nuts, rods and negative space thread forms. Designers use it to add custom threaded geometry to their own OpenSCAD projects without building thread logic from scratch. The library is intended to produce printable outputs rather than serve as a standalone object. Parts generated from it are typically printed in PLA or PETG, depending on the mechanical demands of the finished application.

Update:
Due to some bugs in the initial version, a revision of the OpenSCAD library has been uploaded, please use "polyScrewThread_r1.scad". Thanks a lot to mechadense for reporting the bugs!
This is my humble take on a screw library to be used in your OpenSCAD scripts.
If you are serious, please be, you'll better use http://www.thingiverse.com/thing:8793 syvwlch.
Anyway, I had this thing for months in the lost projects folder suffering from some serious issues, well some of them remain (it doesn't render) and once the dust has been shaken it compiles quite nice and printable things.
Instead of functions, this thing uses loops.
Instead of rotate polyhedrons, this thing draws the polyhedron in a new set of points.
Just a couple of comments to help using this thing:
- I've found that a resolution of something like 1.5mm (PI/2 is what I use the most) works very well for threads that will be used with nuts made with a resolution of 0.5mm.
- I've printed the threads with a very low infill (0.2) but for the nuts, setting up this value (I've used 0.45) helped a lot with the overhang issue.

Printing Poor man's openscad screw library
For Poor man's openscad screw library we would normally reach for PLA — it is the easy, economical default and suits the majority of models. We set the layer height, wall count, infill and supports to suit the model and how you will use it, and those choices are already priced into your instant quote. Want a specific colour or material? Tell us and we will match it where we can.
