11" x 2.15" shadow box

11 inch by 2.15 inch deep shadow box. I placed 8 #4 or #5 screws into the corners along with glueing the corners together for extra support. I used an 11" (2mm deep) square craft board on the back with the attachment pieces also sized for #4 or #5 wood screws, I beveled the openings for the screws to allow them to sit flush. use a wire to the two top screws to hang or place hanging clips on the top holes since those wont need to support the craft board. Print same board twice for full model
