This is a 5x7 picture frame with picture support and a brace to hold everything together. Created a slide in stand that attaches to the holes in the picture brace.
The picture is placed in the frame, then the back plate, then the brace to hold everything in.
Printer frame face down with no supports. Brace and back plate can be printed flat with no supports as well. Does require a wide build plate to lay flat.
