Blocks for Round Balls

I was wanting something to keep those round balls from moving all over the shooting bench.
Beginning with a small piece of Walnut, several holes at 3/8 inch (dimples) for .490 round balls. Shown in the first picture are five of those round balls in a larger block.  The smaller block shows five holes and seven holes. The larger block has staggered hole spacing for fingers to easily grasp those round balls and the holes are about 1 inch apart.

Next pictured are six .375 conicals in the smaller block. This block has on three of its sides different count of holes. 5, 6, and 7. As seen in the second picture, there are six holes on top and seven holes at the front side. These blocks have one coat of finish. The larger block is 1/2 inch thick by about 8.5 inches long and the smaller block size is 1 inch square by about 4.5 inches long.
