A similar tile to the divert tile, but without the trap part. The balls fall through the bottom path, resetting the arms on the way down. When the arms are closed, they open to the other side when hit with a ball, similar to how a newton's cradle works.

-- Printing - All models are scaled up 10x. Print one base and two arms for each tile. When assembling, the arms should be tightened just enough so that a ball can fall through them from gravity alone.

Thanks and have fun!
