Parametric Goban / Go Board

thingiverse

This is a goban I designed in FreeCAD. The line spacing is regulation size so one can use regulation-sized stones, though the line width is wider to make the lines easier to see. In a 9x9 configuration, it's just small enough to print with an ender 3, if you move the bed clips out a bit and use a thinner brim. FreeCAD (or at least the version I am using) takes a long time to update the model if you enlarge the board, but it should work given enough time. The user is advised to print with something that does not easily warp. I used TPU, which was challenging but did work. TPU yields a rather "grippy" surface compared to a wooden board, which I personally do not mind.
