Congratulations! You now have your first paper-printed 3D model! Now all that is left to do is pretty it up! Since I made a duck I decided to spraypaint it with Spray-On Rubber!
(get it? Rubber ducky!). You can pick this up at your local hardware store or follow the link to the home depot page. After that I just used regular craft paint to on his feet, bill, and life-preserver.
THAT'S IT! Have fun bringing your ideas to life! Why not make your kids (or yourself) a toy. Make yourself a new hat! Make a landscape for your model train set! Whatever you decide to print out, have fun with it, it can be addictive!
