Ender 3 Y-axis stepper motor damper spacer

thingiverse

I bought some stepper motor dampers for my Creality Ender 3 3D printer but they wouldn't fit because my stepper motors have press-fit pulleys which are hard to remove. For the Y-axis I made this spacer so the damper can be used without altering or vandalizing the stepper motor in any way. To mount this thing to your Ender 3 (not Pro) printer you need to move both the Y-axis endstop and stepper-motor-mount to opposite sides, mounting from left to right and endstop from right to left. Mount the spacer and damper to the stepper motor, remembering to run the belt through before bolting everything together. And mount the whole thing to the motor mounting plate. I reused most stock parts but you are left with 2 stepper motor screws and 2 endstop bolts as they need to be replaced by 2 M3x25 bolts for the spacer and 2 M4x30 bolts for the Y-axis endstop, actually cutting 2MM off each bolt. Make sure that after mounting it the belt is still centered and please check belt tension. In the pictures I used rings for spacing the endstop but now I have made a printed spacer for this. I have also designed a solution for the X-axis which can be seen at https://www.thingiverse.com/thing:3271077
