Apex - A 3D Printed Marble Machine

Introducing Apex—an entrancing 3D printed marble machine. Watch the marbles carefully as the spiral lifts them up, and they weave down a plinko board, stairs, and various other tracks. The machine uses 8mm or 5/16" marbles (the distinction is negligible), but can be scaled up proportionally to use larger marbles.

Note that the 8mm ball bearings are considerably smaller than normal marbles (which allows the design to be more intricate).
