Dungeon tiles
thingiverse
These are 1/60" (30mm) tiles for use with miniatures. You can connect them together to make dungeons. Instructions Print out the pieces you want to build a dungeon. Note that you need to print out the "tile_key" pieces to connect the tiles together. The .stl files should be usable on a printer. I added versions of the walls with detailing on the exterior (the "2" versions). Let me know if you like these better. The .scad files are the sources--they were created using OpenSCAD. If you find this useful, feel free to let me know.
With this file you will be able to print Dungeon tiles with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Dungeon tiles.
