The movable dungeon grid for War Gaming Tabletop and Dungeon is really awesome!
The dungeon grid is manufactured in a complex 3D printing process. Thus, extremely realistic shapes, structures and contours are achieved. Furthermore, the dungeon grid convinces with a very high level of detail. The iron grid is anchored by a metal guide bar, which is pushed through a cavity of the door frame and the hinges of the grid. The rod can then be fixed to the lower end of the cavity, for example with simple plasticine. This prevents the rod from slipping out. Thanks to the metal guide rod we achieve a strong robustness of functionality. Other products that are printed purely in 3D have a disadvantage here, as the hinges tend to break out! Then you have to buy a new door!
