#3dpetprint I've always wanted to shred the slopes with my cat Otis, but I doubt I could get him to stay on a circular sled, yet slide down a hill on one! This enclosed sled is for any scaredy-cat who you seek to enjoy thrills with. The large window allows can be covered with thin plastic once you have your kitty inside. Make sure you bundle them up!! You may want to split the file depending on your printer's build volume.
