This product is delivered as a .ZIP file pack containing STL files for use on a home 3D Printer. The files are set to 28mm scale but can be rescaled before printing.


The skeletal swirls and bony ridges beneath your feet serve as a constant reminder that this is no ordinary place you’ve arrived at. But this is no time to lose your nerve. There’s a job to do, and for now that means you must follow the tunnels, working your way in deeper.
