Anyone Seen or Heard of These Tracks?

[Super]

I see what you mean but I can't get a clear picture of what the coupling looks like. Thats is one of the reasons why I wish this fellow would show how some of the customs were made. Hmmm, wonder if he has a web site or FaceBook type site where there would be more about the customs.

I am sure you are probably right about the track being 3D printed Finno.
