Go stones making kit

thingiverse

This kit can be used to make Go stones with self-hardening clay.The bottom part (black) can be used to first “cut” a consistent amount of clay.Wrap the clay with plastic wrap to avoid it sticking to the mold, then squeeze it between top and bottom part. For very smooth stones, you can sand them (PLEASE ENSURE YOU USE NON-TOXIC CLAY)The 23.5 version is slightly larger to get slightly biggers stones for blank. Size after sanding is ~22mm. Depending on how you sand them, you might try shrinking the model e.g. printing at 95% size to get 22mm stones.Right now I am using 22.5 for white (yielding ~22.1mm stones) and 22.5 for blackYou can use the refiner tool to hold the stone while sanding it.
