I designed This ice scraper to help wipe off the snow and ice from my goggles without scratching it. This model has a small hole designed to be used for a laniard or cord loop to ensure that you don't lose it while also being small enough that it's not annoying to have in your pocket. 

I printed this in PLA, mostly because I deal with a large amount of ice on my goggles and not snow, but there is no right answer for material choice, and something with a softer durometer would be a  good choice for cleaning snow off your goggles.
