Customizable gonggi stone (공기,공깃돌)
thingiverse
Customizable stones for the Korean game of gonggi ( https://en.wikipedia.org/wiki/Gonggi ). The round stone was created as a star with high rounding. The sunshine stone was created as a star with low rounding and caps. The hexagon stone was created as an hexagon with cone rounding (bevel on top) and caps. This prints well on my cheap printer even with the overhangs due to the caps. To make shallower angles, raise the round_height parameter. It is recommended to raise the resolution ($fn~=40, twist_slices~=15) before the final openscad rendering. Making square gonggi is easier, take any dice model or intersect a cube and a sphere: intersection(){ cube(size=18, center=true); sphere(r=12, center=true); } What's next for gonggi stones, Gomboc ?
