About this 3D model

This thing inserts into the cassette player and holds my GPS because i dont want it where it usually goes. My GPS plays MP3s so i want easy access to the screen, right by the stereo. You can place your phone in there as well, just make sure you modify the box to fit your needs. I included 3 different shells for you to work with. One for Droid X both with extended battery and standard will fit., Razr MAXX and my GPS unit.
