Kazoo
thingiverse
Here's a homemade kazoo crafted in Inventor - all you have to do is hum into the narrow end and it will emit the sound out of the other end. Up top, there's a thin membrane that helps amplify the sound. This one-of-a-kind creation can be 100% printed out on your 3D printer.\n\nPrint Options\nRafts: \n Who Cares?\n \n Supports: \n Definitely Yes
