When designing items, you often get many ideas, but to fully do them justice, I like to see the real thing in person to achieve the best outcome. I had been looking at doing this type of design for a while, but could not find one to take proper inspiration from until my family took a walk along the coast from Teignmouth to Dawlish, where we came across an ideal design during the walk. The pictures are of the bridge with my children on it.
With all my designs, I like to add some variation, and therefore I have done three different length bridges and also a version with a step at the end. This way, hopefully, I will cover the needs of most people using this design. The design has been designed in such a way that I can produce the bridge in 8mm increments if needed, but you do see this in the design pictures, but the lines don’t appear on the print.
The model comes in two lengths, 70mm and 102mm; the versions with steps at the end are 8mm longer, making them 78mm and 110mm. The model is about 20mm high and 18mm wide.
The wooden bridge has been designed at OO Scale of 1:76.2for HO print at 87%, 1:87 Scale,for TT print at 63.5% 1/120 Scale,for O UK print at 175%, 1:43.5 Scale,for O 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 can’t guarantee its printability)
The example in the pictures were printed on an AnyCubic Proton M3 3D resin printer.I recommend printing these on a 3D resin printer to get the best print definition.As per normal with my designs, there is a balance between accuracy and printability, hopefully not affecting the look of the model too much.
