I got tired of speding countless hours cutting faces off mouthpieces to make mouthpiece trainers for friends and students, so I 3D modeled this as a universal mouthpiece trainer!

The trainer allows you to form your embrochure (either on your horn or off it) and view it through the side cutouts while buzzing. this is super useful for anyone trying to make minute adjustments, anyone who recently got braces/aligners on/off, or someone trying to make sure they have good and consistent airflow.

Sanding/smoothing of the rim faces is not required, but highly reccomended
