Two speed gearbox. Part 2

This is a demonstration model of a two-speed gearbox mechanism.
The main parts of the mechanism are the driving ring, the shifter, and the clutch gears. The driving ring has tabs on the sides that mesh with the clutch gears and a notch around the middle that meshes with the shifter. The clutch gears are different sizes, resulting in a different output speed when engaged. They have round holes in the middle rather than regular axle holes, allowing them to spin independently on the same axle. The shifter, when moved, also moves the driving ring, which meshes with one of the clutch gears. The clutch gear meshes with a normal gear, rotating the output axle.
