Model Railroad, Covered Bridge
thingiverse
This model railroad bridge design, inspired by photos found online, is specifically designed for O27-scale trains but can be scaled down for S, HO, N, or Z scales with certain adjustments. Printed in one piece, the bridge features a tin roof and boards along its sides. The full-size version took around 20 hours to print on a Makerbot Replicator2. To print smaller bridges for other scales, adjust the scale accordingly, using parameters provided for each train scale. Expect some challenges with adhesion and warping due to the bridge's length, but these issues can be managed with proper printing settings and techniques. Remember that this design is not based on a specific prototype and may require additional straight tracks for optimal fit with your model train setup.
