Large motorised marble lift, 13 cm (+ 3 marbles) compatible with GraviTraxUnser Sohn hat es zum Geburtstag bekommen und das Riesenrad wurde sofort in seine GraviTrax-Bahn integriert. Er ist überglücklich.

Large motorised marble lift, 13 cm (+ 3 marbles) compatible with GraviTraxKundenservice sehr gut. Die Funktion hat durch den Transportweg etwas gelitten. Die Kugel bleibt immer mal wieder hängen.

Who are we?
I’m Matt. It all started with an adapter to join my son’s GraviTrax and Duplo. Today I design every part myself, print it in bio-based PLA less than 40 km from Grenoble, and my kids test it before it goes on sale.
