This Pedestrian Bridge is designed for G Scale. It might be possible to scale it down for O scale, but small Balustrades etc are 2mm in G scale. There are 20 STL files. Some need multiple prints. Details are below. I assembled my model without glue, but pieces can be glued if desired. No. Description. 4 B_Stairs 3. This is the only item that needs support. 2 B_Stair_Platform. Small for straight stairs. 2 B_Stair_Wide_platform. To build as shown in pictures. 2-4 B_Stair_supports. 4 needed for wide platform. 2 B_stair_couplers. These couple bottom of stairs to stair platform., 4 B_Bridge_support. Tall support for bridge. These supports have holes in the bottom for connecting together.They are taller than stair Support. 2 B_Bridge center support. Print vertically with a raft. Leave raft on bottom support for easy assembly. 2 B_Top_landing. The platform at the top of the stairs. 1 B_Center_landing. Small platform on top of center support. 1-2 B_Bridge.

Bridge supports have holes in the bottom so supports can be stacked on top of each other. Bridge supports are also taller. Handrails are not symmetrical. The top handrail is 4mm wide while the Balustrades are 2mm. Lay them flat when printing. Please post a comment if you print this model.
