self Supported Bridge

grabcad

Leonardo da Vinci designed the self-supporting bridge in 1486 for Cesare Borgia, creating a simple structure that could be assembled by troops without woodworking skills. The bridge featured two components—five short poles and ten long ones—that would stand independently upon assembly. To enhance stability, a weight might have been tied to the central cross member when not in use, while planks across the cross rails facilitated quick movement of troops. This model is 3D printed with white strong and flexible polished nylon plastic for a smooth matte finish. The design's simplicity demonstrates Leonardo's brilliance.
