Holds a pool cue more securely on the side of a table while waiting your turn.Printed upside down so there is no need for support.I printed with 3 permiters and moderate infill (20%). Earlier itterations were printed with more fill to make them heavier, which somewhat negated the need for nonslip pad.Glue a bit of non slip pad to the bottom where it sits on the table for a more secure hold.
