iPhone 6s Otterbox mount

I originally made this a year ago for the iPhone 5 Otterbox defender, which I never shared as there were several versions. One mount for the door for my printer, one as a holder for my passenger side headrest to keep my daughter entertained in the car, and another as a mount on the wall for charging.
This current design has been revised for all three uses. The three holes in the internal face accept M3 screws for mounting to a wall, acrylic, or any other flat surface. The Pair of holes on the top and bottom are two run twine through to then be tied onto the headrest poles in your car. The opening in the lower front also allows for the phone to be inserted or removed even if you currently have the charging cable plugged in.
