Customizable Ontario License Plate
thingiverse
UPDATE: Check out this updated version of the file that lets you pick from all Canadian Provinces and Territories (http://www.thingiverse.com/thing:1781423) Customizable Ontario License Plate for Cars. This one's part of a car costume (http://www.thingiverse.com/thing:1770501), with 120mm x 50mm as the default size. This file works best with the Windows Font "Univers 57 Condensed". If your PC doesn't have it or you're using Customizer, it will automatically switch to a standard font. I used a blue Sharpie marker for coloring in the letters. Inkscape and paths2openscad (http://www.thingiverse.com/thing:25036) helped me turn a blank plate (jpg) into an SCAD file, then I added the text. You should be able to easily duplicate this for another province or state. UPDATE: I've added a feature that adjusts the text size so it fits on the plate even if the wrong font is missing.
