One of my great passions is bridges and bridge architecture. I modelled this simple Warren Truss bridge from pictures. The overall bridge dimensions are to scale to suit a standard Ninco track section but the beams are not exactly to scale. I increased the cross-sectional thickness of the beams to allow for printing with a 0.4mm nozzle. Care must be taken when printing this model to ensure clean, sharp corners and edges. This will ensure a good fit of the components and ultimately a good looking model. I have not included the bridge abutments as there are so many variations. If this model generates any interest, or you have any suggestions, please leave a comment. Good luck !
