Just cross posting this from the 3D printing thread.
Check out our universal cell phone mount. It has a pretty standard ball end to attach to your favorite style holder. We have a clamp style and a MagSafe style shown here. The print is attached with 3m VHB double sided tape to the dash. We've uploaded it for free to download on our site.
