Gecko Kazoo

I present a kazoo with an unusual shape :)

 It has a membrane in its tail and sounds like a usual kazoo.

You can print it with colors like in print profile or color it as you wish in the Bambu Studio or after print. 

After printing, find a thin piece of foil, place it on the tail and screw it. Do not tighten completely. The foil should have some space to vibrate. I use foil from thin disposable bags. 

While playing, you can try tightening and unscrewing the cap to fine-tune the instrument

Have Fun :)
