Poster Hanger Frame

Give your posters, art prints, and canvas charts a clean and natural display with this 3D printable poster hanger frame. This design creates a classic wooden-style poster hanger using cylindrical rods that clamp the poster securely without damaging it. Each rod features a center slot that allows the poster to slide in easily, while snap-in wedge retainers lock the poster in place so it stays flat and secure. Because the rods are longer than most printer beds, they are split into two printable halves and joined together using an internal press-fit coupler. The coupler slides into slots on each half and holds them firmly together without glue. The top rod includes a hole for a screw-in hanger hook, allowing the frame to be hung directly on a wall. Printed in wood PLA and lightly stained, the finished frame closely resembles real wood and works beautifully for vintage charts, posters, art prints, and educational prints.
