Ball Chip Collection

This is a collection of rock climbing holds for indoor rock climbing walls. There are four and each has a different radius for training foot and hand holds. Once printed, they should be sanded with 60 grit paper, spray or roller-painted with acrylic paint, and have clean sand poured on top. The sand will be glued to the surface by the paint. Once the paint dries, brush or even sand off the excess sand and then spray or roll another coat of paint. Once dried, the rough surface will be rough enough for a sure grip, but not so abrasive to be uncomfortable.
