This is a part of a parent collection of many different marble tracks compatible with Marbleworks Grand Prix marble set. See remix source for larger collection of marble tracks.

This design allows for splitting marbles into two lower tracks. This model is quite close to the original Marbleworks splitter in look-n-feel. The design features a Y-pointed split point in the middle. Empirically it splits ~50/50 with a good print and an unbiased spin from the top tower. The ramps are shielded to prevent marbles from leaving but still allowing for you to see them choose a path. It took several design passes to get all the right shield points and ramp angles for a good piece. Hope you enjoy it!
