A simple 3D printed plastic tunnel for an N-scale train track.
Train not included. Tracks not included.
Since we 3D print these tunnels ourselves, we can fulfill most custom requests (length, radius, width, height, and shape).
3D printed pieces always come with some minor surface artifacts. You can cut away any strings, and you can lightly sand the surface. But don’t go too deep, because the outer shell is only about 1 mm thick.
If you plan to paint it, consider starting with a filler primer. This can help fill in the seams and other artifacts of the 3D printed model.
