i saw 2 other Saturn related things on thingiverse, so at least 2 of you have a 3d printer!
If you're looking to print a customized dash phone mount, here's a link to thingiverse where i designed one that fits a saturn ion. It's still undergoing changes and needs some refinement, but if you're skilled with openscad you can probably take it and remix it to nicer looking.
Basically you'll need to modify the phone cutout module (you'll need to learn open scad first). define your phone size, expand or shrink the cutout for the screen and buttons and usb port. After that, export and print.
