Hold the Phone!
thingiverse
I purchased a car window phone mount on Amazon, branded "WAZE", which has an excellent app. The mount consists of two parts: a suction cup and bendable arm with T-Slot, and an adjustable padded phone cradle with T-Slot. Unfortunately, the cradle broke, so I replaced it with a new one that fits perfectly in the WAZE mount's T-Slot. I have printed both the cradle and mount in nylon (flexible) and ABS (less flexible), both of which work well and lock tightly to the base. The settings used for printing were: layer height 0.25, perimeters 3, top solid layers 3, bottom solid layers 3, fill density .4, perimeter speed 66, infill speed 66, travel speed 130, and nozzle diameter 0.50. The WAZE car mount can be found on Amazon at this link: http://www.amazon.com/Wazes-Universal-Mount-your-Smartphone/dp/B004O7S7Z0/ref=sr_1_2?ie=UTF8&qid=1372130216&sr=8-2&keywords=waze+phone
