Phone Boom Box

This works great on my Galexy S8, but may need adjusted for other phones. Let me know what you think! It amplifies the sound of the speaker built in the phone. As for the structure of the inside of the print, it is done mostly with round tunnels for sound travel, so that it is self-supported durring. It looks like an old-school boom box with the tall side speakers. Hope you enjoy my first upload.
