Multi-Mallet Crank Drum

thingiverse

When you crank the handle clockwise, the gear shaft moves first and every connection between each shaft turns the next one into action. Each mallet is forced upward by the base gears, but because of a pre-programmed slip in the base gears, it also falls freely and strikes the center of the drum exactly on target. Designed to permit effortless spinning of the gear shaft with zero resistance, the shaft supports ensure that each pair of gears stays perfectly aligned throughout the process.
