These things really do work! They dampen the vibration from the stepper motors, making them quieter. Can be used primarily on X and Y steppers since they do the most work.
NOTE: Price is for 1 damper
For the X Axis, you will need 2, M3x6mm screws.
If your pulleys are pressed on such as with the Ender 3 PRO, this will not work without replacing the stepper motor and pulley. If your motor pulleys are removable, you will be able to use stepper dampers without any additional hardware as the pulleys can be adjusted to compensate for the added damper.
