I created this model of a pedestrian bridge to replace a previous model which was stolen. It fits the german “Spur H0” with a scale of 1:87. It is now freely available on Thingiverse.com:
First I took careful measurements of the old bridge’s placement and sizing. This gave me the overall shape of the bridge. I looked for the legal standards to determine the exact slope for the stairs and their step size to fit the H0 scale. Then I added fitting rails and some decorative support structure to give the bridge a nicer appearance.
The bridge is printed in separate pieces. This simplifies the print process as well as the storage of the bridge. The different parts are:
- Left Stairs
- Right Stairs
- 2×2 Handrails
All parts can be printed laying or standing flat on the build surface and no support is needed. All parts fit a conventional build plate with dimensions of 20x20cm.
The Bridge includes two wooden sticks (3.8x40mm) as a design element. This can be made from a shashlik skewer. Alternatively, print it yourself.
The walls of the stairs feature a 3D stone texture. This increases the .stl file size, but makes a much nicer appearance and simplifies painting. The Bridge also includes a plank texture.
