Track Pack...Anyone Seen Them?

[Super]

I couldn't find any 3D Print models for Real Class type tracks when I looked on Thingiverse yesterday, which surprised me a bit . I wonder if anyone has seen any in other places, or any videos showing them?

I don't know anything about Thingverse but I came across these in a video yesterday... same guy in the videos Chrisjo Linked to on the first page of this Thread?

I know this fellow has more but I can't find out how to access a Thingverse page for him if there is such a thing.
