Wacky Kazoo Collection

Heres a butt-ton of kazoos designed in blender.

Here are the 6 different sized membranes I used:

Stupidly Small: x0.6
Smallboi: x0.8
Normal: x1
Bigboi: x1.2
Giant: x1.4
Obscenely Big . x3

For the washer and the locknut, just scale them by the correct multiplier (see above).
Good luck.
For the Obscenely Big membrane, use some kind of paper, the regular plastic doesn't work.
