About this 3D model

Variations on a golf ball... My first attempt didn't survive meeting the club, this one is sturdier. The hollow one survived one hit with a putter, but not the driver. The version with internal heavy support survived at least one hit with the driver. (But, being white, it was lost. Next one I make will be fluorescent red.) The -sh version is hollow, but with external supports. The -ss version has heavy internal support and thin external supports. The -out version is the outside only, drawn in blender. The scad version hollows the outside from blender and adds the support pieces. I challenge someone to figure out how to do the blender part in openscad! (Wtih parametric depth or something...)
