Piccolo Trombone

thingiverse

As a trombone player myself, I thought it would be awesome to play a piccolo trombone. After realizing both are pricey (for me) and that I could design/print one, I started working on it. In the end, there are 5 parts - the Bell Curve connecting to the Main bell makes printing the whole bell easier. Then there's the two slides, one fitting into the other, changing notes as you go. Finally, there's the mouthpiece which fits in the longer section of the inner slide. Conveniently, the mouthpiece is the same as a trumpet mouthpiece, so if you happen to have a trumpet, it works with it surprisingly well. Just keep in mind this design isn't perfect regarding offsets and tolerances for parts to fit snug or loose - the mouthpiece might crack plastic if inserted too hard, and slides might not fit at first, requiring sanding.
