If you own a GraviTrax® marble run, you know the problem: the most exciting track ideas fail for lack of height tiles or curves. That is exactly the gap our construction accessories fill — precision 3D-printed, compatible with GraviTrax® and GraviTrax® Junior. Here is an overview of which set does what.
Note: NEXCAPE accessories are independently developed third-party add-ons, not original Ravensburger products. GraviTrax® is a trademark of the Ravensburger Group.
Why height tiles are the bottleneck of every track
Height is literally the energy source of a marble run: the more elevation at the start, the longer and more action-packed the track. The base sets, however, are short on height tiles — anyone building large constructions needs more.
Height tiles 9-piece set (3× 100 mm, 3× 50 mm, 3× 30 mm)
The essential expansion: three sizes for flexible build heights, stackable and a precise fit with the original pillars.

Telescopic height tiles XL & Mini — the flexible solution
Our cleverest part: telescopic pillars that extend steplessly to exactly the height you need. Instead of combining tiles, you simply dial in the precise elevation — ideal for fine-tuning gradients.

Curve stones set — routing on your terms
With additional curves you route the track wherever you want it — tight turns, S-bends, returns to the launch ramp.
→ Curve stones set
For the little ones: GraviTrax® Junior
The Junior system uses its own, larger connectors — standard accessories do not fit there. That is why both expansions also come in a Junior version:
What we focus on in 3D printing
- Precise fit: connectors sit firmly yet remain child-friendly to release — just like the original.
- Stability: dimensionally stable plastic that supports tall towers.
- Made in Germany: every set comes from our workshop in Wildberg.
FAQ
Does the accessory really fit? Yes — standard sets fit GraviTrax® systems, Junior sets fit GraviTrax® Junior. Please check you have the right system; the two are not cross-compatible.
Is this a Ravensburger product? No, NEXCAPE is an independent accessory manufacturer. The sets are developed to be compatible but are not original accessories.
From what age? Same as the respective marble run system: GraviTrax® is recommended from age 8, Junior from age 3 — small parts do not belong in the hands of children under 3.
More height, more curves, more track: you will find all sets in our GraviTrax® accessories category.
