Helix Double Loop Track for Hubelino
Print Profile(1)
Description
Overview
Upgrade your marble run with this high-speed Helix Double Loop. Instead of a simple circle that kills momentum, this track is mathematically engineered to taper from a large loop into a smaller one. This matches the natural deceleration of the marble, allowing it to complete both inversions smoothly every time. The approach track features dual rails to center the ball for a fast, friction-reduced launch.
