Trumpet Practice Buzzing Utensil

Buzzing, i.e. playing the trumpet mouthpiece without it being attached to the trumpet, is an important part of the practice routine of many trumpet players. So important in fact that a device was invented which enabled you to attach a mouthpiece to a trumpet in a way that it enables the player to buzz while holding the trumpet in an accustomed fashion. The original device is called the \"Berp\". This is my attempt to recreate it for all the 3d-printing brass players out there.
