Free standing display holders for photographic backgrounds. Ideally designed for A3 sheets, but will take larger. The background sheet is held in the deep channels of a left and right stand. Although the stands have a flat base to stay in position, I have incorporated a feature that allows them to fit on 5mm foamboard (or anything else at 5mm thick). When fitted onto a length of foamboard, the two stands are held in position and more permanently fixed.No support is necessary for printing and I suggest normal setting with 20% infill.
