I did a bit more work trying to figure this problem out, and I came up with
the following code. My only concern is that some of the dimples don't line
up right, and the spacing isn't correct all around, except for the equator
ring. It is also a big resource hog.
#declare DimplesPattern =
union {
sphere {
0,
3
translate <0,0,-32.35>
rotate <0,8,0>
}
/*
sphere {
0,
3
translate <0,0,-32.35>
rotate <7,4,0>
}
sphere {
0,
3
translate <0,0,-32.35>
rotate <-7,4,0>
}
*/
}
#declare Dimples_Equator =

}
