Holes on this goban can host 16mm marbles and 22x8.5mm go stones. You can adjust sizes in scad files (it's the blue goban on the photo with several gobans).
This work is done in collaboration with Nerv Project ASBL, Ligue Braille, Liege Hackerspace and Belgian Go Federation.
You can contribute to this project on our git repository here: https://procrastinator.nerv-project.eu/kujiu/goban
Note: In the future, we'll create some modules to use the board as map on tabletop RPG.
The author marked this model as their own original creation.
