Simple Screw Thread Library Turbo

thingiverse

The original library was developed by marcaxi and refined by rubisco2000. I rewrote it to create a single polyhedron instead of combining triangles with hull operators and unions, resulting in massive performance boosts. On my machine, the example parts took approximately 1 minute and 24 seconds to render originally, while with these improvements they rendered in just 12 seconds. The created geometry is remarkably similar, with only a minuscule tolerance used to prevent point overlap. Unfortunately, the preview functionality still doesn't work as intended, but the final rendered objects are acceptable.
