Apex - Marble Machine

SummaryIntroducing 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. I also made a motorized add-on here: https://makerworld.com/en/models/585030 The machine uses 8mm marbles (see Bill of Materials) (the distinction is negligible), but can be scaled up proportionally to use larger marbles.
