Brio E1 Track - Containment Walls

I designed these as we purchased the Express Ramp from this Etsy supplier:

Whilst the ramp is great what we found was that once the trains made it to the bottom by gravity they would shoot off into the sunset.

There are various iterations of the design, from the simple being a containment wall to a half tunnel.  

I've printed using Amolen Wood Colour PLA for the base and Proto-Pasta Black HTPLA for the initial wall and Proto-Pasta Ice Translucent for the half tunnel overhang.

If you want the three colour effect, the colour changes should be at:

0-12mm for the base
12mm-37mm for the wall
37mm to end for the translucent overhang

The models are male and female based as you can't really flip a curve upside down to change direction, can you :-)
