This is a mechanical gearbox toy designed to convert a simple hand-crank motion into the rotation of a logo mounted above the base. Turning the crank drives a compact transmission made up of four spur gears and two bevel gears, carefully arranged to redirect motion from the horizontal plane to a vertical output. The bevel gears handle the change in axis, while the spur gears manage speed and torque transfer, making the internal movement visible, readable, and satisfying to watch.

The project is designed as both a functional mechanism and a visual object, allowing the user to clearly see how rotational motion flows through the gear train from input to output. All parts are modeled with 3D printing in mind and are intended to be easy to assemble and operate by hand. This gearbox toy represents my fourth project in Blender, focusing on improving mechanical accuracy, part relationships, and overall design clarity compared to my earlier work.
