poster board holder

3D Printable Poster Board Support Foot – Front View This is a compact, desk-friendly support foot designed to securely hold ultra-thin poster board (approximately 0.3 mm thick) upright for photography, display, or presentation purposes. The form is minimal and optimized for 3D printing, featuring a wide, flat base for stability and a narrow vertical slot precisely dimensioned to accommodate standard poster board thickness with a snug press-fit. Key features include: Central Vertical Slot: 0.4 mm wide, 25 mm deep, allowing the board to seat cleanly and remain upright without adhesives or clamps. Embossed Inset Panel: A shallow rectangular cut-in adds subtle surface detail, useful for branding or label marking if desired. Rounded Base Corners: Prevent warping during print and provide a clean visual profile. Overhang-Free Geometry: All vertical walls and features are designed with clean, self-supporting angles to eliminate the need for supports during FDM or resin printing. This part is p
