The mechanical marble run from Ugears combines sophisticated model building with kinetic motion. Crafted from 266 precision-engineered wooden parts, this functional marble run model is assembled easily by slotting the pieces together without glue or tools. The system is powered by a side hand crank that sets visible gears, a central spiral lift, and a vertical lifting device into motion. Colourful glass marbles navigate through varied track sections such as curves and cascades. Measuring 28,5 x 26,3 x 27,6 cm, the model offers fascinating insights into finely tuned wooden mechanics.
