After having to fix the Y stop limit switch 4 times, I had enough and designed this to mount the switch to a static position on the printer frame. Works perfectly on Hictop 3DP08 or 18 and may fit other models.

To mount this, you have to loosen one of the y axis guide rod bracket/ mounts and remove the M3 screws. Insert this mount and use M3 screws (you may need longer ones than those supplied with printer) to reattach the guide rod bracket.
