PocketBone - A Fully Printed Piccolo Trombone V1.1

Yep, it's real, A fully functioning piccolo trombone, can hit all 5 positions of a real one, uses any standard trumpet mouthpiece.
While you can 3d print the mouthpiece, it sounds much clearer with a metal one as the printed version is quite buzzy.

Note as of 5/21/26

Sorry about the false alarm about V2.0 coming out soon at Christmas time. School has hit me like a truck recently so I haven't been able to work on this much at all. I will put out a new note when I have a timeframe figured out for 2.0 release

Version 1.1 (Current Version)

No longer requires the CPVC pipe, now includes a printable version
Leadpipe is still fairly fragile
Printable outer slide makes movement very loud without quite a bit of sanding
1 or both of those will be fixed in version 1.2 (2.0 if both)

Version 1.0 
Uses CPVC as the outer slide, PVC will not work as it is a different size.
Leadpipe is currently very fragile so try to be careful!
