This design was created for a friend that wanted a car, cell phone holder for his Droid Razr Maxx. The design was created to house his Droid that included and outer case. He wanted to use double sided tape with velcro so he could switch between his wife's car and his. We are both pleased with the outcome and found only two items that needed addressed. I added an extra back brace on the far side and extended the slot on the top for access to the volume buttons.
