Stackable Concrete Barriers (N Scale)

This set of scale-accurate, stackable concrete blocks brings industrial realism to your N scale model railroad or diorama. The blocks are inspired by real-world modular systems used for silos, retaining walls, sound barriers, and more.

Available in 7 sizes (from 1×1 to 4×2), each block features top "nubs" and bottom recesses that allow for easy, Lego-style stacking – just like the real thing. The modular design lets you build custom structures for freight yards, depots, construction zones, or industrial backdrops.

Optimized for clean and easy FDM printing, these blocks print support-free and come out with a realistic concrete-like finish – no post-processing required. Mix, match, stack – and bring your layout to life with endless possibilities.
