Passive Amplifier (Megaphone) for the Galaxy S4 Armored PEPK case

thingiverse

I whip up a killer beat at the office using my phone and full-volume rips through my battery, so I fashioned this boombox dock to crank it up halfway, keep my music hot, and my phone fully juiced. There's a hole in the base that lets me snake a charging cable from the back up into my device. The middle bit's perfect for those bigger cables that can't handle flexible goodness – you wanna keep 'em charged while jamming out to tunes. On the bottom of this rig, there are two spots just begging for magnets to attach. I use these metal carts to stash it, but don't want my baby goin' rogue and tumblin' off when things get rough. I drilled a soda cap down into that back pipe and super-glued it in place – now it's a cinch to snap on any soda bottle without worryin' about those threads gettin' all gummed up.
