The file 'Working Air-horn 3D Printer Model' is (stl) file type, size is 38.1KB.
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.
If you don't want to have to print the diaphragm; I have found that a peice of paper works well!
I printed this with ABS, I'm not sure if other filaments would work or not but please let me know if you try and how it turns out.
Update: I have uploaded a new version of the case in an attempt to eliminate the need to push the horn in and out. Hopefully, if you use "Base Airhorn_2" the air-horn will work as soon as you put it together. I have left both versions of the base since the placement of the horn is very sensitive; If needed you can print the original case to get the best sound.
