Mini Trombone

thingiverse

There a couple other piccolo trombones on Thingiverse - however, I decided to design my own take on this instrument. The slide is slightly longer than a regular piccolo trombone giving it a lower sound. With a tight lip embouchure you should be able to get a brassy sound out of it and be able to use the slide to adjust pitch. There are four STLs attached: the inner slide, the outer slide (which goes over the inner slide), the connector from the inner slide to the bell, and the bell itself. I decided not to design my own mouthpiece - instead, print the trumpet mouthpiece found [here](https://www.thingiverse.com/thing:772936/files). This [mouthpiece](https://www.thingiverse.com/thing:291388/files) is also quite good and is more aesthetically pleasing, although I prefer the former. It should fit fine into the inner slide. You can also use an actual trumpet mouthpiece. If you wish to edit anything about it, I've attached the Fusion 360 project as well. I recommend using supports on all the parts except the bell. On the slides, it may also be a good idea to add a brim if your bed adhesion isn't great. Concerning post printing, I didn't do too much. I only used the the Ender 3 clippers to get rid of some artifacts, but you shouldn't need to do much sanding. You can listen to an audio sample of what it sounds like [here](https://soundcloud.com/user-602826613/minitrombone-sample/s-QEoKAzZUPVg).
