UPDATE
I have made a tutorial for a DIY bed leveling sensor. I uploaded the Marlin 1.1.9 config files together with this thing. Enjoy!

UPDATE
I have designed an end stop flag with integrated M18 bed leveling sensor mount. The distance is 48mm to the right (X) and 0mm in Y.
My printer is still out of order, so I cannot print it right now. If someone volunteers and feeds back, I will be grateful!

UPDATE
After more comments about the clearance for the belts, I changed the design of the lower screw support [ender_x_damper_v5.stl]. I have made it with the same clearance as the original x-stop bracket, it should be OK now.
I have added extra support for the x-stop switch compared to the original design.

My printer is currently out of order, so I cannot print it myself. I will come back soon when I'm back in business.

Thank you for the support, again and again! :-)

This model allows to mount a stepper motor damper on the X axis if the motor has a press-fit pulley that cannot be removed without the risk of damaging the motor.

The assembly requires the following fasteners:
2x M3x25 screws
2x M3x20 socket head screws
2x M3 nuts
6x M3 washers (not necessary but recommended).

NOTE: YOU HAVE TO HAVE A BOOTLOADER and an editable version of the firmware!
Due to the fact that the motor is assembled backwards the motor will turn in the opposite direction.
To fix this change the value of #define INVERT_X_DIR in the firmware.

The video tutorial for the installation is here
