I designed a simple holder for the iPhone 5 to work with the dashboard vents of my 2008 Volkswagen GTI.
I have been using the holder for a few months now and really like it.
Feel free to share and/or to modify the design and let me know what you think!
After two failed prototypes, I found the perfect mix between stability and simplicity and had fine-tuned the viewing angle of my design. It slides easily into the dashboard vents and a hook prevents it from falling out. I opted to add five pieces of 0.5mm thick fabric (shown in red in one of the above illustrations and included both as PDF and DXF drawings) to protect my precious phone from scratching.
For printing on a Solidoodle, I broke the product into four parts and the files contain 3D data both of the Solidoodle-version, as well as of the complete object -? maybe you can find a better way to deconstruct and print it?
