This variation on my custom-fit sunglasses case for my Ray-Ban Aviators, like the others, is rigid enough to protect the glasses but slim. Like the MK2 this one has a shirt clip (and supports built in, since programmatically generated ones make too much of a mess). The MK3 adds a snug-fitting cover.I printed with a raft, but without supports. You will want to cut some soft felt to line the inside on at least one side so the glasses are not scratched.
