The Caret Splitter sits opposite the (top of the) Triple Splitter. It is the small section of track which spans the end of the medium marble resting point which does not involve the Triple Splitter. I named it Caret Splitter because it is shaped like vaguely like a caret ^. It is actually shaped more like the Japanese character へ, when viewed from the direction the marbles will reach it.
February? 2019: Will be augmented with Caret Splitter Right Hand Inner Side.
