Minimalist Y rail endstops

thingiverse

This is about the smallest inline endstop I could come up with for the Y rail. I needed the limit switch below the Y-carriage for another project I am working on. it's angled to line up with the Y belt anchor bracket for either the trinitylabs or makerstoolworks Y rails, but should also work on other projects. As there really isn't much plastic for your anchor bolts to bite into for the Y switch mount itself, you will need some washers. Right and left versions included, for use on either side of the rail. Instructions print it with support. I found end printing was easiest. then trim the keyway notch to fit your rail and screw it down. The Y switch is held on by bolts threaded into the plastic itself. seems to be holding up fine so far, though I may try for a nut backed one later.
