This fullyfunctional, custom 3D printed Gerstlauer Infinity coaster featuring a vertical lift and 3 inversions took over 1 and a half years of free time to construct.

The layout, track, train and supports were designed with a combination of Blender, Fusion 360 and patience.
The track, train and supports were all printed using an Ultimaker 2 and Creality Ender 3.
