Corner fastener

This is a remake of standard RV corner fasteners that you sometimes find in older RV's. I use them myself and I have to say that they are better than the originals. Although they are not the prettiest and do not have a cover lid so you might want to keep them out of sight.
If anyone asks, I can make prettier versions with a cover lid as well but I just didn't have the need for myself.
Suggested printing material : PETG or ABS.
