Working Air-horn

This is a working air-horn that is completely 3d printed and it is loud! I made the this for the #Makeitloud challenge. Once you print this it is as loud as you can blow! I have been able to achieve 110 decibels with a nice print of the diaphragm. If you use flexible filiment for the diaphragm you may get a much louder sound. Unfortunately, I do not have any flexible filiment to try.

When printing the diaphragm print the diaphragm_2 first; I have had much better success from this one.
