Flip it over depending on where you prefer the hanger hole - top, sides, or bottom. Next, drill a hole from the back and insert a set screw, securing it firmly into the corner of your foam core board. For hanging purposes, utilize wood screws, nails, zippy ties, string, or whatever materials are available to attach through the printed mounting holes. If screws are used, consider enlarging the front hole slightly to recess the screw head. After printing, drill a hole on the side you intend as the back and thread in a set screw for added stability.
