N: DIY-viaduct for KATO’s Unitrack

For mobile layouts KATO’s Unitrack is the first and only choice in n-scale and one of the best track systems in general:

The system includes viaduct tracks and as I have made a viaduct for my Minitrix unloader, a hade fun to create more viaducts, compatible to KATO’s original viaduct tracks. The advantage of my viaducts is, that it uses simple unitrack rails, just clipped into the viaduct, so you can use the rails with viaducts or as simple rails. Furthermore it’s designed in such way, that below track you can route cables, what is not possible with the original viaduct rails. Finally you can find here viaducts for track geometries, that are not available as originals, for example R216-45, and all the 15deg-curved tracks.

It prints just on plate without supports and 0.4mm nozzle, but with very fine layer height of 0.08mm to build up the overhangs. Larger items are available with built-in rafts to ensure print quality at the outer corners (I use the Bambu X1C, and the heat from the build plate isn't sufficient at the edges, so a raft is necessary to prevent warping). Rafts are easily removed after printing with a sharp knife.

Hope you enjoy these extended possibilities to create viaducts with KATO’s great track system. Happy printing and a lot of fun with your model railway layout!
