I'm an even bigger noob than you, but I liked the idea of Minkowski, so I googled around a bit. Found this: https://github.com/openscad/openscad/issues/610 From what they say, it looks like upping the resolution of your sphere makes the dimensions more accurate. I tried it with your code, putting in "sphere(r=2.5, $fn=20);" to define the sphere, and measured something much closer to 35. Ediby maso - OpenSCAD
