This blower does its job efficiently, blowing air with precision. Built for enjoyment, it also serves as a functional tool for ventilating fires and other areas that require airflow. When paired with my motor, the blower's operation is characterized by a distinct noise level, drawing 3.5 amps at 12 volts - unfortunately, I couldn't measure its rotational speed in revolutions per minute. Assembly of this blower requires six M3 screws, two of which should not exceed 5 millimeters in length, depending on the motor used. The impeller's dimensions are circular with a diameter of sixty millimeters and a height of twenty-seven millimeters. It can be securely pressed onto a three-point-one-seven-millimeter motor shaft. A Fusion 360 model for this blower design is available at https://a360.co/2uSV85f.
