Interested in 3D printer for music (Score 3, Interesting)

I'm a musician. I'd love to test some designs for trombone mouthpieces on a 3D printer. Trombone mouthpieces have been round for a hundred years because that's easier to manufacture on a lathe. What if brass mouthpieces could be different shapes? oval, oblong, rounded triangle? A 3D printer would be great for that kind of experimentation. Likewise, I'm also interested in unusual capo and string mute designs for a guitar.
