UPDATE 12/5/2015
I redesigned the gear train, please print the gear files ending in "_UPDATED". The original gear train used 3:1 ration, which proved to be to high, and required too much torque to turn the handle. The new gears are a 2:1 ratio, and work great. Unfortunately to get the speed seen in my proof of concept video, the higher gear ratio would be needed. My new gear ratio works out as follows. 1:1 Bevel gears, 2:1 intermediate, 2:1 intermediate, and 18:16 final (this goofy ratio was needed to not have to redesign the case). That give a final ratio of 4.5:1. This means the final design is not as loud. The videos below show the final design in action. The video doesn't really showcase the sound very well, I believe the noise cancelling of my phone mic picking up the gear noise better than the siren noise. I assure you, while the final design is not at loud as my Proof of Concept" video, it is certainly still loud enough to grab someones attention.
