Model Railway Concrete Platform Footbridge 3D print model

On a recent trip to Eastleigh with my son we went via Gillingham Station (Dorset) and spotted this concrete footbridge and I thought it would be an ideal design to add to my collection of items.

The design is made up of multiple sections that can be glued together to complete the bridge, you can either build it as a U shape or can put together in a Z shape. Smoke deflectors are optional extra if you want them.

The middle span comes in three sizes of 125mm, 150mm and 175mm, this is ideal for single or double track and dependant on space you have. The design is also designed to sit on the platform.

The design has also been designed to be printed on a FDM printer or an resin printer (for resin the centre section is dependant on the print build plate area of your printer).

designed at OO gauge, 1/76.2 scale but can easily be scaled for other gauges.for HO gauge print at 87%, 1/87 Scale,for O gauge UK at 175%, 1/43.5 Scale,for O gauge International print at 158%, 1/48 Scale,for N gauge print at 51.49%, 1/148 Scale, (Caution: I have not printed this model in N gauge so I can’t guarantee its printability, recomend resin over FDM)

The examples in the pictures were printed on a Bambu Labs A1 FDM Printer.As normal with my designs, there is a balance between accuracy and printability, hopefully not affecting the look of the model too much. This design was especially difficult to get a balance between accuracy and printability.

For FDM printing I used a 0.4mm nozzle and a layer height of 0.12mm using PLA filament.
