MEGiPHONE V1 and V2 Megaphone stands for iPhone 5c and probably 5 as well

I designed these for my final project in class last semester, thinking that maybe someone else would want one too. To be honest, I have no idea what the best printing settings are since they were printed on a $10,000+ printer. I'd recommend going with v2, as it'll cut your printing time roughly in half. V2 boosts the sound level almost twice as much. As for V1, to be frank, I never actually printed one, so I'm not even sure how much of an amplification boost it provides. These should definitely be printed out in inches. Also, just a heads up, the megaphones and case piece aren't exactly the same width - I plan on revising that with v3 and making it better overall. It's possible you might need to do some sanding on the connection point.
