Earbud Box mix Phone Holder

I designer the phone case, and it is easy for one hand hold.
In addition, this case can let phone stand on the table, when you watch movie.
And I mix "http://www.thingiverse.com/thing:36321" core part, so you can storage your earbud.
I stretch the earbud storage side of "core.stl", and it can storage big earbud.
