I want to print a relatively fine thread on the inside of a tube (and on a mating plug). What's the practical limit of thread pitch (or TPI)?
The tube is only 2mm thick wall, so can't go with a coarse thread. I have printed 20 TPI, but have followed it with a tap, or pseudo-tap. How fine a thread can one print without being a superhero? I'd guess variable layers would be helpful.
Just looking for some guidelines so I don't waste a lot of time on this idea. It would be better if it was imperial, so I could make the pseudo-tap easier, but I'm just looking for how small a pitch is reasonable. Is 40 TPI possible? 32? Otherwise I have to glue this, and I really don't want this to be a permanent joint - I need to be able to take the assembly apart.
