The Y endswitch holder was the only part of Ghruum's collection that I could use for my Vevor 3018 CNC. Fortunately, he provided a STEP file, so I could isolate it from the other parts. I also added a new actuator wing. The whole design is quite specific to that machine and my use case … but maybe it helps somebody else :)
Print one limit switch holder as-is and one mirrored. Screw the limit switch to the holder with two M3 screws. Screw the limit switches to the Y support rail using T nuts and M4 screws. Screw the actuator wing to the table using two M6 screws and T nuts. Adjust the position of the switches to trigger shortly before the table bumps into the front and back walls.
