This a bed scraper I designed to clean off things such as skirts, brims, prime lines and other non model objects. I use instead of metal scraper to not destroy my PEI beds and you can do the same. Or say you want to print many things one after another and just need to quickly clean off the mentioned objects off the bed and don't want to grease up the bed with your fingers, this bed scraper is the exact thing you've been looking for.
