I found one in a book of manly quilts, or maybe it was sports quilts. I can't find the book, but I found the pattern for the soccer ball. I made one for my nephew, and I didn't keep a photo. Basically, it's a pentgon in the center, with hexagons the same side length around it, with the outside pentagons appearing as obtuse triangles rounded off. The obtuse angle in the triangles is about 150 degrees (90 + 60 degrees). The circle is just a little larger than the hexagons surrounding the center pentagon. PM me if you need further help. Maybe i can get my nephew to send a photo.
Actually, it looks a lot like the one posted above in the link
