About this Product
This scraper is designed to scrape the loose (and semi-loose) processing powder out of the maze paths of my maze puzzles. [http://www.shapeways.com/shops/amazing]

The scraper in WSF material will work when you handle it gently and use a small metal tool (screwdriver) when you find a part of a maze path blocked. The scraper in stainless steel is more rigid, and can scrape blockages from powder directly clean.
