Gringotts™ Bank Marble Run

Assemble me. Watch marbles roll through underground vaults!

Meet the Gringotts™ Bank Marble Run DIY model, a new addition to the licensed Harry Potter™ series by Ugears. Unlock the hidden vault system and reveal what lies beneath — the legendary location where gold and treasures are securely guarded deep within subterranean chambers.

Ugears Gringotts™ Bank Marble Run is powered by an electric motor via a USB Type-C connection, ensuring continuous marble motion. The model features a two-unit foldable design — the bank and the vaults — which can be securely fixed in either position. An automatic lift mechanism raises the bank building to expose the underground treasure system below. 

Dual-tone LED lighting enhances the display: warm light illuminates the hall chandelier, while cool lighting highlights the hidden vault network, creating a striking atmosphere, especially in low light. With its richly detailed interior — grand columns, chandeliers, and authentic goblin imagery — the model beautifully captures the spirit of this high-security fortress.

Marbles flow through branching tracks in an endless journey, taking a different path every time. A waterfall-style conveyor then lifts them back to the start, completing the cycle for non-stop mechanical motion. When you're done playing, simply press the special lever to gather all the marbles into the built-in storage compartment. For total immersion, the kit includes a souvenir — a collectible Galleon coin you can use as a lucky memento or turn into a display or wearable souvenir coin. Multiple tracks, moving elements, and detailed interiors turn this model into an interactive experience that is just as captivating to watch as it is to build.
