Publisher Blurb: DRAGONLOCK™ Ultimate is an all-new 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. A standard wall piece costs around 45 cents in plastic to print yourself, far cheaper than factory made terrain! All of the models shown were printed at 150 micron resolution, a common standard on most economical 3D printers. A nice starter printer that can print these files starts around $220 (see our F.A.Q. for more info on printers, printing costs, filaments, and more, over on the FDG website forums.) This set includes: • Straight Wall 2 • 2x2" Tile • Dragonbite™ Clips • Instruction Guide
