A simple, single-file modeled ISO thread module for OpenSCAD. Supports external threads (bolt) and internal threads (nut) with top and bottom chamfers. CSG compilation takes a few minutes, but produces functional metric and imperial threads. The default clearance parameter can be decreased for larger thread pitches and/or smaller layer heights.
