Bring motion and fun to your desk with this hand-cranked marble machine! This model features a functional lift mechanism that transports the marble to the top, where it then drops into a small gravity maze.

• Mechanism: The design utilizes a smooth hand-powered gear and scoop lift (blue parts) to elevate a standard small steel marble.
• Components: This project is a great showcase of mixed materials, combining 3D printed parts (PLA) with laser-cut clear plastic sheets for the side panels and maze path, allowing full visibility of the action!
• Fun & Educational: A perfect introductory project into kinematics, gears, and physics. Great for a STEM gift or a mesmerizing desk toy.
• Parts Required: Requires 3D printed components, clear sheet material, and one standard-sized steel marble.
