I had an idea about laying out my grip and pap on a piece of cardstock. Drew my finger and thumb holes, grip centerline, then my midline and pap. Marked off the midline in 1/2" increments. Cut it out, keeping very close to the holes and the pap circle. Kinda looks like t on it's side. The card stock bends enough so the layout will conform to the ball. Of course it's not as accurate as laying a ball out but if you want to see the pin to pap and cg to pap on previously drilled balls it works pretty good. Also is fairly accurate on showing layout positions on undrilled balls. Plus it was cheap.
