3xM10: Voronoi Chess Set with inlets for 3 x M10 Nuts

Add even more heft to move the center of gravity even more toward the base by pressing three M10 nuts into the inlets at the base of the figures. Use some glue if the nuts sits not tight enough. If you print this on an FDM printer: Scale it up by 5-10%! It is easier to insert the nuts and glue them instead of sanding it if it is to narrow.
