For each tile, print yourself one of dungeon_stone_corner.floor., dungeon_stone_corner.wall. and a base of the same size (1x1 - 4x4). The tiles are in 25mm square basis (which matches Dwarven Forge). If you want that size, print without changes, and print one of the 25mm bases. If you instead want inch squares, scale the street tile on X and Y by 101.6% and print one of the inch bases. Finally, if you want wyloch style tiles (1.25" per square) scale the X and Y by 127%.
Note: All bases for OpenForge Dungeon Stone are kept in their own thingiverse entry: OpenForge 2.0 City Street Bases
