Have you ever needed a vibration motor, but realized for a heavy duty one they aren't very cheap?. Well I found a simple solution to adding your own weight to a motor. You simply have to connect a outside of the nut that is a reasonable size and weight onto the motor rotor. To connect the nut to the motor. Simply put adhesive on the motor rotor and the nut, securing them together. Its that easy!
