HO/OO Model Train Track Spacing Tools

thingiverse

Combining my latest hobby with one that's been around since I was young, I've created a collection of track spacing tools for modelers who use flexible track systems. Four distinct items make up this set, each printed separately to ensure precision and accuracy. A simple block is designed to test rail spacing, and it's measured precisely at 16.48 mm - just enough to provide a snug friction fit between 16.5mm OO/HO rail. Next, I've paired two blocks side by side and bridged them to achieve the correct track spacing for parallel rails. To ensure tracks are not only separated by the right amount but also perfectly straight and parallel, I've printed four blocks together in a single piece. My latest addition is a platform gauge specifically designed for British OO scale, which should provide the precise separation from the rail and the height of the platform - a feature that still needs to be thoroughly tested.
