Customizable N Scale Footbridge

thingiverse

Updated 9/15/2018: Added Customizer support for simpler cases, published OpenSCAD file for interested parties. Three versions of an N Scale double track footbridge are available. The model resembles a vaguely UK or Australian pattern and connects two 1" wide platforms with a 2" pit between them. The center span is 50mm, the full span 78mm, the overall width 102mm, the walkway width 12mm, with a headroom of 26mm. Version B has been printed on a FlashForge CreatorPro in ABS using default settings (0.18mm). It includes STL files with supports designed in since the Slicer's auto-supports feature was inadequate. A raft is recommended but not essential for printing. The three variants can be modified, reassembled, and stretched in your Slicer or STL Editor to suit different locations. This design was created in OpenSCAD as a generator of complex T Scale and Z Scale footbridges. This version has been cleaned up with additional detail added, although it is still somewhat sparse for N Scale.
