I love the Dungeon Block system but I always disliked how the basic grids were only available in 3x3 format, and were only loosely held together by the interlocking frames. So I set out to design a variety of bases with different grid sizes and with several different interconnection systems. This version uses GridLink connectors, simple to use and print connectors that will hold the grids in place when they are put on the table. The grids are about 11mm taller than the default dungeon block base grids and so are not cross compatible. Included in this set are grids ranging in size from 3x3 all the way to 9x9. At default scale, the normal Bambu printers can just barely fit a 6x6 grid and corner frame. This set includes all the base grids, matching corner and edge frame pieces, all the necessary connectors for both grids and frames, and a bunch of extra useful goodies. Future sets will include additional connector types (OpenLock and Magnets, for sure), frames pieces integrated with useful game aids, and whatever else catches my fancy. Enjoy.
