Jet ski propeller 3D print model

Propellers, often shortened to props, are sometimes called screws—and it's easy to see why. To push a screw into the wall, you apply a clockwise turning force to the head with your screwdriver. The spiral groove (sometimes called a helical thread) on the screw's surface converts the turning force into a pushing force that drives the screw into the wall and holds it there.
