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

Designed these for my final project in a class last semester and figured some people may want one. No idea for best printing settings as these were printed on a $10,000+ printer. I would suggest v2 as it'll take about half the time to print.

V2 Amplifies the sound close to double.
Not sure how much V1 amplifies the sound as I never printed it.

These should be printed in inches. Also I know the megaphones and the case peice aren't the same width, planning on making a v3 and making it bett
