This model was inspired by a failed project that produced a shape very much conducive to scraping. Traditional scrapers don't allow for the user to press down very hard and I got this idea to create a scraper that you can press down on while you work. It works quote well and requires very little support to print. Feels great in the hand and does a great job of scraping and cleaning even surfaces. The underside is made such that it reduces the surface contact area and allow for easier forward motion. Would love to head your ideas on how you would improve this design.
