Mechanical AMplifier
myminifactory
A Smartphone Amplifier, designed to boost a phone's sound using a parabolic dish that directs the audio. This device should work seamlessly with any smartphone that measures less than half an inch thick and 3.5 inches wide. For optimal amplification, place the phone's speaker precisely one inch away from the slot opening and just below its top edge by about an eighth of an inch. The closer you get the phone's speaker to this focal point, the more pronounced the sound will be. The printer-friendly dimensions for this device are 6.5 inches x 6.7 inches x 5.5 inches. For best results without any support material, print the dish facing downwards.
