I use my phone for music at work and using it at full volume drains the battery quickly, so I designed this megaphone dock so I can play at half volume to keep my music loud and the battery full. There is a hole beneath to allow a charging cable to snake up from the rear and into the phone. The middle section is used mainly for larger cables that don't have a flexible cable while you want to keep it charged while playing music. On the bottom of the stand, there are two spots for magnets to be placed. I use metal carts which I place the dock on, but don't want to risk it getting jostled and falling off. I drilled out a soda cap and glued it inside the rear pipe to allow easy attachment of the soda bottle without worrying about the threads wearing down.
