Starting diagonally opposite Triple Splitter, the Lowest Small-Medium Splitter is a long track next to The First Track. It cannot handle large marbles like Triple Splitter but it guides small and medium marbles after they come down the left (shorter) side of the Caret Splitter.
Its first guard rail is Bar Below Circle by Caret Splitter which worked for medium sized marbles, but didn’t work for small marbles.
Its second guard rail is The Lowest Longest Separator which keeps small marbles from falling onto The First Track.
At the lower end, its third guard rail is Small Marble Saver which prevents small marbles from falling into a little hole after Lower Curver off the Lowest Small-Medium Splitter.
Its fourth guard rail DNE as of 9 June 2025 will (probably) connect from Paul to Caret Splitter Feeder Extension Reflection Stanchion and Backpack Jack will soon start bringing it into place.
History:
Upon testing, I discovered medium sized marbles could not pass Caret Splitter Feeder Extension Reflection Stanchion because The Lowest Longest Separator forced them into the Stanchion.
