I just completed the remix of the Galaxy S4 case by RealAbsurdity. I want to thank him for providing an amazing base model to work from. It adds a pocket that allows the sound to travel to the front edge of the case rather than through the back. In my search for a case that does this, I haven't found anything that solves this problem. I will add pictures once I print it on my dual replicator in the next couple days. If anyone tests this and has suggestions for changes, please leave a comment and I will gladly make alterations. After my first test print, I will be considering adding additional space to insert small strips of foam pad to further surround and insulate the speaker port from vibrations.See RealAbsurdity's printing instruction, as I believe they will yield the best results. http://www.thingiverse.com/thing:99152/#instructions
