Marble Machine M3 - Single Arm Lift

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. Here’s what makes it exceptional:
