3D Printed Screw Threads

I'd find it hard to resist the urge to hit that with a heat gun to smooth it out.

Crazy accurate modelling. Does it hold a seal?

I would like to do something to smooth it out but it's fine as it is. The threads have a fit typical of metal ones but it won't whistle. I think because the PLA doesn't resonate like bronze, brass, or iron would.

I expect I could run steam through it. Once.
