We created or own beerpong formation.
It works great for the standard beer pong cups (0,4-0,5l).
It has the option to fill the holes with magnets. We drilled some holes under our beerpong table and filled these with magnets too, so you can easily adapt your table magnetic with the formation.
If you dont want to have the magnetic feature you can just glue the magnet closing twice in the holes.
If you are unsure about the click system we added some dummies for testing - please check these before printing, so that everything will work.
Happy printing :)
