Uses stock parts!
Allows you to add a damper to the Ender 3 Y-axis on models with a press fit pulley that isn't easily removable. The metal motor bracket should be moved to the opposite side of the Y-axis bar along with the endstop switch. The new endstop mount will allow you to mount it this way using stock parts. See the second picture for details.
The "Y_Axis_Damper_Mount_Set" file will print both parts at the same time and save you a few minutes.

Tips are appreciated if I saved you a few dollars not replacing the pulley :)
