3DL Core Set
One System. Endless Dungeons.
Most dungeon terrain sets give you pieces. 3D Legend gives you a complete architectural system.
With traditional terrain sets, once you build a layout, the same pieces recreate the same dungeon again and again. 3D Legend was designed differently: each terrain element is part of a highly modular system that allows components to transform and adapt to different configurations. Instead of creating dozens of static models, the system uses interchangeable modules and inserts that dramatically expand the number of possible combinations.
At the core of the system are modular wall sections designed to support multiple configurations. A single wall element can be adapted using interchangeable inserts to become a solid stone wall, a heavy wooden door, a barred prison gate, or an alternate texture variant. Doors and structural inserts are designed to be swapped quickly, allowing you to modify your dungeon layout between gaming sessions without reprinting entire pieces.
Whether you play tabletop RPGs (D&D 5e, Pathfinder, OSR), dungeon crawlers, or build massive display dioramas, 3D Legend lets you create a new dungeon every time you play. Print exactly the pieces you need, build your layout, and face its perils!
