Trumba - A Tuba mouthpiece to Trumpet converter

After not playing my trumpet for many years, rather playing low brass I found getting that buzz quite challenging. So to procrastinate working on the buzz I made a simple converter that took my Conn 120S helleberg and fit into the trumpet. I printed this with Pla+ and can get lower octaves/higher octaves out the middle range buzzes don't work may work better with a different material.
