Designed to be printed in 2 pool cue increments to support 2+ pool cues. This particular design was made with 8 pool cues in mind, hence the reason for 12 connectors to be used in the holes in the side of the top/bottom pieces. Using some super glue along with the connectors to align, chaining 4 of them together at the top and bottom yields a pool cue holder for 8 pool cues. The holes in the middle of the front/back of the top/bottom are for 1/8" screw for mounting to the wall.
