GENIALITY SIMPLICITY self-supporting bridge

GENIALITY + SIMPLICITY = Leonardo Da Vinci's self-supporting bridgeThe original project of this simple and brilliant bridge is present in sheet 71 of the Codex Atlanticus (the largest collection of projects and drawings by the famous Italian genius Leonardo Da Vinci).Only two modules - no support - the number of modules to print is variable because the bridge can be very short, using only 6 A modules and 3 B modules or very long, adding 2 A modules and 1 B for each new span (the recommended number of spans is 5). For assembly, follow the sequence shown in the image.In the introductory figure you can see the final result we want to obtain. It is a self-supporting structure, that is, it stands up by itself thanks to its own weight, without the need for nails, glue, ropes, etc.The true genius of the project lies in its resistance to heavy loads. This is in fact directly proportional to the weight that passes over it. In other words, the bridge is designed to increase its load-bearing
