Trumpet Kazoo

The kazoo is played without a mouthpiece. The mouthpiece is optional and makes the trumpet look prettier. You can also use it to create a ‘trumpetsound’. 

Part 2 is plugged into part 1, the valves (you need 3 of it) are glued to part 2. 
You have to cut a piece of foil (diameter 17-18 mm) and place it in the hole.

Part 1 is printed with supports.
