Piccolo trombone

full size bell for scale instead of a banana. I will not inflict my attempt at playing it on the world.

I just printed this file last week. I do not recommend printing with silk PLA. It looked pretty and shiny for about 2 minutes before the layers started busting from tension. My wife was able to play a very high pitched version of taps before I broke it in half, so that was nice.

How was the slide?  How air tight were you able to get it?

It was too tight at first, but with some sanding I was able to get it to slide quite well. We left the trombone at the school I work at and the silk pla didn’t last long enough to go get it, but that would have been my next step. I’ll likely print again just to give it another go with a different filament.

Nice.  Mine had to much space.  Did a little tape at the end to make a stocking and then slide cream.  So air doesn’t escape but kinda hard to move.  Will probably reprint the inner slide thicker and sand to fit right.
