I'm Pete, the maker behind The Chalk Shop in Sturgeon Falls, Northern Ontario. I cut real metal signs every week, and these are the same tested files: clean SVG, DXF and PDF for plasma, laser, CNC router, Cricut and Silhouette. Rustic wildlife, cottage and Christmas designs. See finished signs at https://www.thechalkshop.ca and find more files at https://www.etsy.com/shop/TheChalkShopStore
