RE: I designed 3D models of various types of Zampoña, Andean panflutes.

This is interesting and reading your post I've also learnt something. I know pan flute, it's traditional in my country and we have a famous pan flute artist as well, Gheorghe Zamfir, you may have heard of it, if you're in the industry.

Congrats on the 3D printing, I've never thought I'd see 3D printed pipes, but everything is possible these days 😉
