Customizable GPS Sun Shade Visor

I needed a shade from the sun for my Garmin Nuvi 1300. Customize your own. Be warned... after a couple of days in the hot car, it warped. It was printed in PETG filament. I may have to resort to sheet metal.

Customize this in [OpenScad](http://www.openscad.org/) (free). Export to STL. Slice in your favorite slicer (Slic3r). Send g-code to printer.

I would print a partial test print with a zero visor length to make sure you dimensions are accurate. Be sure to flip (rotate on z axis)
