t-trak R12 viaduct corner

thingiverse

Here's an SVG (and STL to show the finished shape) to cut a deck for a R12 viaduct for T-TRAK-N. What you do is cut the shape out on a laser or CNC, then add block/bolt feet (two at each end and two in the middle) and then skin it in handi board. The handi board will probably need to be steamed to make the curve without breaking, I just did mine sitting in a strainer over a boiling pot and kept turning it over until it was soaked. This is designed to take R282mm + R315mm Kato Unitrack.
