Marble Machine M3 - Assembly kit or Pre-Assembled

M3 Single Arm Lift - Build it. Play it. Display it

The M3 Single Arm Lift is a wooden marble machine kit that demonstrates the clever interplay of simple mechanics. A rotating crank works in sync with a lever to rhythmically lift marbles to a higher position. The marbles are then carried upward through precisely crafted holes in a wheel, before being released into a staircase mechanism. This completes a closed loop, readying them for the next cycle. Its straightforward mechanisms offer young children a clear, hands-on view of kinetics in action. This physical, educational gift provides an intuitive way to spark curiosity and inspire exploration in students and young learners. Made from natural solid wood, the kit measures approximately 9.4 x 5.9 x 5.9 inches (240 x 150 x 150 mm) and weighs just 1 kg (2.2 lbs), making it a compact yet engaging display for desks or shelves. Here’s what makes it exceptional:
