An OpenSCAD file for creating DXF files to laser-cut a Shibumi game board.
Export a DXF and use it to laser cut a game board for Shibumi. This file is currently set for 25mm diameter marbles. You might want to measure your actual marbles and tweak the settings. You want to get as small as possible without getting too small, so all your marbles can sit securely in their holes. Also, you might want to reduce your hole radius if your board is quite thin. The marbles should not touch the table-top. (If they do, you can always add feet to the board.)
