Smartphone passive amplifier

thingiverse

Fits nearly all big screen smartphones, and I've had great luck with my iPhone 7 Plus even when it's covered by a leather case. Amplifies quite nicely, and the unique wood print design is sure to turn heads. Prints with less infill, but that means sound quality suffers as a result. For the best results, be sure to print with the speaker opening facing upwards. I've found this makes all the difference in how my prints turn out. I used supports during printing and had no problem removing them afterwards using a pair of tweezers inserted through the phone's opening.
