This is a cordless Minecraft amplifier for iPod/iPhone, unfortunately I had trouble getting this product to sell in color. I think this would be a good product to print because it is cordless and easy to use, you dont have to put anything together or buy anything. All you need to do is insert your device on the top (almost as if your inserting a CD like in Minecraft), then play your music, and it should raise the audio volume.
I used Cinema 4D R16
