I really hate supports and am very happy to be able to print this on my MKS with no supports. It does have some issues on the lower lip, but I will try to adjust the file and update if I get a cleaner print. My goal was to create an attractive frame to gift my children's wallet size school photos to family. I am very happy with the look but will be tweaking the overhang to try to get a truly clean support free print.
