DRAGONLOCK Lost Caverns™ is an all-new 3D printable terrain series that is the culmination of our 19 years of design experience in tabletop gaming, and the master set is so complete we even include owlbear poop!

All models print supportless and are optimized for FDM 3D printers. Lost Caverns™ expansion sets will allow you to customize your dungeon layouts even further with the groundbreaking innovations you have come to expect from Fat Dragon Games. 

New to 3D printing? We’ve got you covered! Fat Dragon Games has a YouTube channel devoted to getting you started in this fantastic hobby, we walk you through everything you need to know to get your first printer, troubleshooting, tutorials, recommended settings, and much more. We also do the hard work for you and provide custom slicing profiles for Cura (a free slicing software) to take all of the guesswork out of the printing process. With full color instruction manuals, custom slicer profiles, video tutorials and build guides, and a Facebook support group with over 13,000 members, no other 3D model publisher provides you with as many support options as we do! A typical dungeon wall can be printed at home for only $0.40, and good starter 3D printers can be purchased for around $180. See our website for more info.
