3D Legends › The System

One System.
Endless Dungeons.

What if a single terrain set could build hundreds of different dungeons? Most terrain sets give you pieces. 3D Legends gives you a system. Masterbuilt for true modularity, dynamic interchangeable inserts, and tabletop immersion.

Architecture & Design

Designed for True Modularity

With most dungeon terrain sets, once you build a layout, the same pieces recreate the same rooms again and again. 3D Legends was designed differently. Instead of dozens of static models, our system uses interchangeable modules and sliding inserts that dramatically expand the combinations from a compact set of pieces.

Dynamic Wall & Floor Inserts

A single structural frame adapts with sliding inserts into solid walls, heavy wooden doors, iron portcullises, or alternate textures without reprinting entire pieces.

Setup in Seconds & Fast Takedown

Clips and releases smoothly with OpenLOCK hybrid compatibility. Modify walls, open secret passages, and reveal trap rooms mid-session with a simple gesture.

Battle-Tested & Convention-Proven

Not just digital renders: fully 3D printed and battle-tested at major European tabletop gaming conventions, including live at PLAY — Festival del Gioco.
