OpenForge is now a patron supported project. I use the resources that my patrons give me in order to get the resources to let me create more sophisticated tiles with a greater level of detail. Please, support me, and I’ll deliver an ongoing stream of awesome gaming terrain. You can find more about OpenForge and Masterwork Tools at our:
Wyloch / TrueTiles - every square is an inch and a quarter (31.75mm). This is compatible with hero's horde, truetiles / wyloch tiles. Scale the tile top when you print it by 127% in the X and Y axes.
Magnetic + OpenLOCK - uses 5mm spherical magnets. 1 each along the center of every square that is on the edge of the tile. Also has an OpenLOCK connector at the vertice between each square.
