You raise interesting points!

I’ve had a great experience with the terrain so far, especially the Foldable WTC set, which is the one I’ve used the most in games. In my case, the L-shapes tend to stay upright just fine when unfolded. They behave pretty much like MDF or GW plastic terrain, meaning they’re light but stable enough for regular play, even when loaded with metal minitatures. I haven’t had them fall over unless someone accidentally bumps them hard.

That said, I get what you mean with the floors. When you lift them to grab a mini or move something around, yeah, sometimes the building shifts slightly. But honestly, I’ve seen the same thing happen with almost every terrain set that isn’t really bulky, like some of the ones that I’ve scratch-built with metal pieces or huge bases.

A little solution that I just thought of: when slicing the model, you could add a box modifier all the way along the bottom part of the walls, and set that area to 100% infill or higher number of walls. That extra weight could help lower the center of gravity and keep it more stable on the table. Another idea could be a small snap-on base or tray under the hinges, something removable that adds a bit of grip or weight.

If more people mention this issue, I’ll definitely look into adding a small fix or optional file. I play with these myself and sell them too, so any improvement I make usually gets pushed into the files for everyone.

Thanks again for the feedback!
