N Scale Refinery Stairs+Railings

Industrial stairs and walkways for a chemical plant or refinery. The staircase and walkways are printed per floor level, to make painting as easy as possible. The legs are printed in one 3-storey piece, and are numbered for assembly. Each floor of the staircase is a separate part, as are the stairs between floors. Assembly and painting are easy.   

The legs are numbered 1-6. I have attached a picture of where each leg should go. The assembly is easy. Just lay out legs 1-3 and glue the platforms to the legs. Then attach legs 4-6 to the platforms, and install the stairs. 
The stairs are an exact fit, you may have to wiggle them a bit to get them into place. The top of stairs rest on a small ledge that is attached to the platform, the bottom of the stairs just rests on the lower platform.
