That looks like one of the plastic golf balls my grandfather used to practice with in the yard when I was young. I followed your tutorial in Blender, and it worked out perfectly. The only difference is in Blender the object is called a Ico Sphere, and instead of chamfer, we would use bevel. My only question is the size of the bevels. Is there a way to tell in Blender the diameter of the holes? I see you using millimeters for the chamfer width in 3ds, and I have my scene set to use metric in Blender, but the bevel is just using the same numbers it always does, regardless of the scene scale? So how do you get precise holes like that in Blender?
