Pool Ball Return System Chalked Up To Ingenuity

Do you play pool? If so, you probably take the automatic ball return systems in bar and billiard hall tables for granted. [Roger Makes] was tired of walking around his home table to collect the balls every time he wanted to play, so he designed a time-saving ball return system.
Instead of falling into the little netted baskets that came with the table, the balls now drop into 3D-printed pockets and ride along dowel rod rails into a central collection box, which is suspended by straps beneath the rack-em-up end of the table. The rails themselves are fortified with ABS ribs that keep the balls from falling through.

Pool is all about geometry, and this really hit home when [Roger] was trying to merge the funnel part of the pocket with the exit chute in the design phase. He covered all the angles with a modular design that lets the chute rotate freely, which takes a lot of stress away from the dowel rods. We’ve got the video cued up after the break, so don’t bother with getting out your film canister full of quarters.

We can’t wait to see what [Roger Makes] next. Maybe it’ll be something like this OpenCV score-keeping system.
