Smartphone Holder for Car Navigation

I have a 2007 Yaris and in the middle of the dash, right in front of the speedometer, there's this convenient spot where I can rest anything flat without it rolling away. So, I made this vertical stand for my iPhone 5s and iPhone 6 (they both fit and with their phone covers on which gives them a thickness of almost 12mm). It's come in very handy because I can quickly grab my phone any time I need it and easily put the holder away, out of sight, when not in use.

If you found this useful, please share your work and be sure to peruse my other submissions which are almost as varied as they are many:

November 11th, 2016 update: Added another version that allows you to use rubber bands to give the thing more grip (instead of using sticky pads like the previous version that can become too dusty/ineffective or fall off). Greatly improved stability during turns.
It also stands the phone upright instead of at a small recline... great
