The Subtractive Helix is broken and very buggy. But it is the most reliable way to get a screw and nut in the software.

Oooh neat!! Is this intentionally designed to be more 3d printable than standard threading? That's a good idea

That’s the idea, though I think I’ve settled on 0.4mm crests and a pitch of 1.6mm.

Still testing but the results I am seeing are fantastic… so long as you don’t use an electric drill
