Propeller for 3-6V DC-Motor

Be careful when removing the supports of this propeller and when attaching or detaching it to the motor, as the blades may be fragile !!I designed a propeller for a 3-6V DC motor. The propeller fits directly onto the shaft of the engine. The propeller has a middle hole that is neither too wide nor too narrow, so it can be easily attached to the engine. I think it is very suitable to use in your projects.
