GRAMiPhone Fixed - iPhone 6 Gramophone Horn

cults3d

This is a compact reimagining of the GRAMiPhone - iPhone 6 Gramophone Horn. I simply corrected the orientation for those who needed guidance. All credit goes to the original creator. This passive amplifier horn boosts your phone's speaker without requiring any power source. The horn profile is based on a Western Electric exponential horn design. It measures 7.5 inches in length and securely fits into the base, thanks to my addition of 0.010 clearance for the phone. However, upon printing, it still presented a tight fit. Update January 5, 2016: I've revised the base to make it more printer-friendly without supports. A small round tube remains inside that may cause issues if not printed with support. The success of this depends on your printer's ability to handle overhang layers. Additionally, I've increased the clearance for the phone, making it a more comfortable fit. The updated base file is denoted by REV 2.
