I used these plans to construct two bins that carry framed work and matted pieces, ready for display. I modified the actual boxes somewhat from these plans, but they give you a rough idea of how to make your own. They are built of 3/4” oak plywood and dimensional oak lumber. Piano hinges are used to attach the tops. I used 4” barrel bolts on the door catches, and 3” butt hinges.
Pictures, and more about the construction, here.
