Speed Pack compatible with GraviTrax.
— Contents —
3 white plates that hold any standard GraviTrax adapter (the green plate in the original box).
3 green compatible pieces that add new options to your runs.
2 zigzag rails: 1 small / 1 medium.
That’s a total of 8 pieces.
The other pieces shown are for display only.
It ships without extra packaging, protected in a bubble envelope. The whole thing is under 3 cm, so it fits straight into your mailbox.

The pack weighs about 48 g.
— How to use —
Requires the GraviTrax base set.
With this Speed Pack extension you get white plates with 6 in/out ports, fully compatible with the original pieces.
3 pieces that allow high-speed turns and entry from all 6 sides, and stand up to the Gauss cannon. The zigzag rails match the boards:
The small one equals 1 square.
The medium one equals 2 squares.
— Design & Making —
I design every piece myself. They were created to complete the marble runs I build with my kids, and I make them on my own 3D printer.
It is printed in food-grade PLA, safe for children. Made from corn starch, it is even compostable and completely child-safe.

— About me —
I’m Matthieu, from France. I love board games and building toys, train tracks and marble runs when they’re fun. Follow the shop so you don’t miss the latest creations!
If you have an idea for a product that would make runs more fun or faster and doesn’t exist yet, just drop me a message — I’d be glad to design it, and if the idea is good the first one is on me.
