The file 'HoMM3 Board Game – Map Tile Grid Magnets 3D Printer Model' is (stl) file type, size is 25.8KB.
The modified grid uses 18x 3mm diameter, 2mm thick magnets (the same ones used in the lid and base). The holes for magnets are 3.2mm and 2.1mm so they can easily be glued in place. This grid is slightly higher than the original, resulting in fewer tile grids in the tile grid holder itself.
