Wooden train track double overpass (Brio compatible)
This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/bZLhpzujKwX
Remix from https://www.thingiverse.com/thing:1280270 - Added a second overpass so it supports three tracks running through it. Printing this and a few of the originals results in a lot of fun.
Supports are recommended unless your printer can handle bridging exceptionally well.
