Some fun designs here.DRAGONLOCK™ 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. Each set is delivered in a downloadable .stl format via our online distribution partner DriveThruRPG.com, and once you have the set, you can print as many pieces as you like and never run out or need to purchase more.
