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.

**Print Settings:**
No supports are required for any of the four files. A layer height of 0.16mm is recommended, at least for the main machine. A printer bed size of at least 170mm x 170mm X 140mm is needed. I suggest a slow print speed for the main machine due to its intricate internal supports. While I strive for utmost file quality, minor variations inherent to 3D printers may result in slight imperfections in the final product (typically easily fixable, in my experience). Uses about 250 grams of filament in total.

**Dimensions:**
-Length: 6.75" (170mm)
-Width: 5.75" (150mm)
-Height: 5.5" (140mm)

*Please ensure ball bearings are out of reach for children under 5, as they present a potential choking hazard. Note that the 8mm ball bearings are considerably smaller than normal marbles (which allows the design to be more intricate).
