This is a windshield scraper I made. It's designed to snap together, but I had to use a little bit of heat to soften the plastic before it actually snapped into place. The reason it's designed to snap together is so that a cloth pouch can be inserted between the front and the handle (just cut a hole big enough to fit the front through), which will keep your hand warm while you are scraping the ice off of your car.

Print both pieces on their side for best results.
