Summary

Inspired by the Mute Cornet / Cornetto, but much shorter scale so it can be printed in one piece. Embouchure should be pretty familiar to any trumpet players. It has a range of one octave that sounds okay, a few more whole steps after that that sound iffy, and then a squeaky hellish no-man's land from that point on.

Supports are recommended for the finger holes but are not needed for inside the bore.
