The ball coaster AKA 'Ballster'

UPDATE (AUG-21-2015): Scaled up to 80mm diameter

You can say that this coaster has balls, and you are right!! It has 36 balls. It is an 'HexagonBall' coaster with 6 edges and 6x6 balls. Not too much to say, perhaps its a little evil. Otherwise it works good, maybe even better than his brother 'Perfster', but this prints slower.

Have a nice BallDrink!!!
