Cornucopia Exponential Horn iPhone Dock

I added a second version split out into four parts for Up! Mini owners like myself... if you have a large enough build tray, don't bother because it's just more solvent bonds, but if a Mini's all you have, give the second set of parts a try. Pro tip: print the end sections of the horn vertically, they come out much better. Pictures of four-piece build have been posted at the end.

I was inspired by brycelowes GRAMiPhone to explore the potential of passive amplification for an iPhone. I loved the idea and how fun the resulting model was, but I found that his implementation took up a lot of space and was somewhat ungainly. I might put it on a shelf but I'd never put it on the nightstand where I charge my phone. Speaking of which, that implementation didn't allow for a power cord, so when your battery is dead, the music stops.
This version uses the expansion horn as the dock itself by bending it in a coil, much like a French horn or a sousaphone.
