Embark on a new Gravitrax Junior adventure with Set #3—an exciting collection of 14 pieces designed to elevate your marble runs to thrilling new heights! The set features two build plates, 11 versatile straight and curved tunnel sections with and without slope, two risers (4u and 5u), and a special funnel element that catches your marble and drops it out at a single point.

Imagine the fun of guiding your marbles through winding tunnels and dramatic drops, then watching them vanish into the funnel before resurfacing for the grand finale. Whether you’re a seasoned builder or just starting out, these pieces bring a fresh twist to your tracks and open up countless ways to experiment. Use them on their own or combine them with other Gravitrax Junior sets to create an epic course that challenges physics and sparks creativity.

Let Set #3 be your ticket to endless marble-powered excitement—get ready to build, play, and share your newest creations!

Disclaimer: Yes I know it has a lot of supports to it, but I like the open design so you can see the marble as much as possible.
