YARQM: Ball with Knurling

Solution to this reddit question:

I used a twisted surface sweep to create a path from the intersection with the sphere, then solid swept (cut) a diamond to form one groove, circular pattern and mirror. Added the hat and rib last.

NOTE: The calculation takes a really long time, will probably lockup or crash wimpy systems, this was a M2 Pro Mac mini with 32 GB.
