With the rise of 3D printing and wireless tech, what if we had a modular system of terrain pieces(Like Gridfinity), that could be set up temporarily at events?

Every member of a club would only have to bring a small section but you could still do really big layouts

My dad's train club, and most of the others I'm aware of, have had modular set ups for about 40 years. They pick a standard for module sizes and where the track connections need to be, and then everyone can design their own module as they like.

For example: NTRAK

Modular is how they’ve been doing it forever, just that a single module is roughly a 6 foot long table (my uncle did this, not me, so I don’t know the exact dimensions)
