Simple Picture Frame

This is a simple picture frame with a typical inset for a photo. I'm using a traditional filament 3D printer, and it's easier to glue the back stops rather than create supports as a single object. The red objects (see image) are super-glued into the back side as shown. The bottom wider back stop holds the photograph in the frame from the bottom. The smaller top back stop helps form the slit for the L-shaped retaining pin (blue object). The L- shaped retaining pin holds the photo from the top. The L- shaped retaining pin is designed to be removable so that you can change the photo in the frame. Do not glue the L-shaped retaining pin into place unless you intent it to be permanent.
