Everything prints at 0.2mm layer height. To print a tile, import tile.stl and then import a pattern as a part. The base is 3 mm high, while the pattern is 1 mm high. When printing with a single nozzle, you can add a colour change command at the 3.20 mm mark to print the pattern in a different colour. For the boards you will need: board-tile.stl: 25x board-border-hole.stl: 10x board-border-tab.stl: 6x board-border-corner1.stl: 4x (2x for the 5x5 board, 4x for the 6x4 board) board-border-corner2.stl: 2x (for the 5x5 board) The naming scheme for the patterns follows the convention on Wang tiles (of which MacMahon squares are a subset) outlined here: http://www.cr31.co.uk/stagecast/wang/puzzle.html https://web.archive.org/web/20210423100709/http://www.cr31.co.uk/stagecast/wang/puzzle.html (archived)
