DRAGONLOCK™ Ultimate an interlocking terrain system that allows you to create fully modular, multi-level 28mm scale dungeon terrain for your RPG or wargame on your home 3D printer. Individual pieces links to neighboring pieces with our exclusive Dragonbite™ clips. Each set is delivered as a downloadable .stl file, and once you have the set, you can print as many pieces as you like and never run out or need to purchase more.

The cost of printing these pieces is very cheap, a chair is about 3 cents, and the large double bed only about 22 cents in PLA plastic, far cheaper than factory made terrain! A really nice starter printer that can print these files starts around $399 (see our F.A.Q. for more info on printers, printing costs, filaments, and more, over on the FDG website forums.)
