Breach Dungeon Tiles — modular D&D base squares + drop-in terrain

A modular dungeon-building kit built around one part: the square base tile. Snap the base squares together into corridors and rooms, then drop terrain into each one to dress the map - floor-texture inserts (stone, cracked ground, cobbles, rubble, fissures), wall pieces along the edges, and scatter props like chests, barrels, statues, trees and crystal pools. Every insert, wall and prop sits on the SAME 27.9 mm square base, so anything in the set drops cleanly into any tile.

Great For Basic D&D Dungeon Building

Instead of drawing the map on a battle mat, you physically build it: lay a path of base squares, slot in floor textures, line the edges with walls, and scatter a few props for cover and flavour. Reuse the same handful of tiles to assemble a different layout every session - a corridor, a treasure room, a flooded cave, a boss arena. Each tile is one grid square, so movement and line-of-sight read at a glance. Pairs with any 28 mm minis (minis are not included).

Print Notes:

• Everything prints SUPPORT-FREE - tiles, inserts, walls and props are designed to sit flat on the bed with self-supporting detail.

• 0.2 mm layers, ~10-15% infill, any FDM printer.

What Is In The Download:

• breach_tiles.zip - the base square tiles + floor/ground inserts + wall pieces.

• breach_props.zip - scatter props (chests, barrels, statues, trees, crystals).

• A few loose sample STLs (a base tile, a cobble insert, a wall) so you can print one straight away without unzipping.

Tiles are one grid square each; inserts, walls and props share the common 27.9 mm drop-in base, so anything from this set can stand on any tile.
