This is a combination of http://www.thingiverse.com/thing:48746 and http://www.thingiverse.com/thing:491121 where the upper bracket of the "Any Phone Car Dock" is merged with the flexible phone holder mount of the "Flexible Phone Holder". This allows the mounting/configuration for holding the phone while having an adjustable mount to hold the phone (without the need for velcro). One is set for vertical mounting, the other is set for horizontal mounting.I used 10-32 x 1" screws and nuts with washers for mounting the holder and mounting bracket to the central arm. The phone holder is best printed with the mount arm pointing up. Supports are required.
