Dungeon Floor Tiles - Assorted Sizes (DND / TTRPG)

For my Modular Terrain System I've been doing a fair amount of work in Geometry Nodes to support building walls and floor tiles. This set of dungeon tiles seemed like a nice little byproduct of this work so I thought I'd take a break from the big set and get this mini set published.

Update Aug 10, 2026:

• Added some sample curved floor templates - added the full 154 files to Patreon freely available (for now)

I've included all of the plain files here and a sample of the 100x100 tiles from a few textured variants (bricks_1, wood_1, metal_1) - ALL of the textured files are available over on my Patreon over here in exchange for a follow. These STL files are free (for now) so if you like them then grab em while you can. If you like the projects that I'm working on you can stick around for freebies like these or support me directly.

The tiles I've published today have the following variants in both 25mm and 12.5mm sizes:

• 25mm x 25mm (1 x 1) - a tiny narrow doorway

• 25mm x 50mm (1 x 2) - a small narrow doorway

• 25mm x 75mm (1 x 3) - a medium narrow doorway

• 25mm x 100mm (1 x 4) - a long narrow hallway

• 50mm x 50mm (2 x 2) - like a doorway / corridor

• 50mm x 75mm (2 x 3) - slightly longer doorway / corridor

• 50mm x 100mm (2 x 4) - a long corridor

• 50mm x 150mm (2 x 6) - a very long corridor

• 50mm x 200mm (2 x 8) - a bizarrely long corridor like something out of a Tony Jaa movie or right out of Old Boy

• 75mm x 75mm (3 x 3) - a small room

• 75mm x 150mm (3 x 6) - you get the idea

• 100mm x 100mm (4 x 4) - a normal sized room

• 100mm x 150mm (4 x 6) - a slightly longer normal sized room

• 100mm x 200mm (4 x 8) - a much longer normal sized room

• 150mm x 150mm (6 x 6) - a large room

• 150mm x 200mm (6 x 8) - a longer large room

• 200mm x 200mm (8 x 8) - a big booty large room

I also made some corner tiles - wide ones are 2 tiles across whereas the narrow ones are just a single 25mm tile

• 100mm x 100mm wide

• 100mm x 100mm narrow

• 75mm x 75mm narrow

• 50mm x 50mm narrow

Similar to my terrain set these tiles have a 2.8mm gap that is 1.5mm deep around the squares - this way you'll be able to use my interior walls with these. A nice little flourish (I think) was that I included the displacement in the gutters. If you use the 12.5mm set then the walls can be placed in half steps which allows for a little more breathing room.

Unlike my terrain set - these floors are only about 6.5mm tall because they don't need room for openlock clips. They're all meant to be loose laid but if there is interest in ones that can be clipped together you could use my modular terrain set instead or bug me here and I'll work on publishing these with clips as well.

I completed my quest for 1000 models in 2025, built a castle / fort in early 2026 so now I'm working on enhancing this modular terrain system. You can follow along with me on Thingiverse, Printables, Cults3d or join in on the discuss on Patreon here (as well as get codes for exclusive downloads on Cults3d). There are dozens of us over here so come and join us!
