Yes.
According to the picture of thing 2078121 (https://www.thingiverse.com/thing:2078121), it seems that the author uses an inductive sensor on the extruder. With this combination, the z endstop is replaced by the inductive sensor which detects the aluminum bed.
On my own printer, I switched to this combination last fall, and I don't use anymore this adjustable Z Endstop.

With the inductive sensor, I encountered the same problems as with the endstop switch. This lead me to make a derivative of the whole extruder ( https://www.thingiverse.com/thing:2580899 ) which is my new solution to this problem.

Concerning this adjustable Z Endstop, you can eventually customize it to your new things with OpenScad ( *.scad source files are included in thing files) and eventually publish it as a derivative.

I encountered similar problems when converting my eMotions Tech's Prusa I3 from version 1.0 to version 1.5. At first I didn't re-printed every things and I didn't noticed that some things had differences of just a few millimeters. I ended up with a broken extruder and problems on the z axis. Fortunately I could repair it with wood, screws and a hot glue gun ... and reprint the correct matching things .

Unfortunately it does not work with this (https://www.thingiverse.com/thing:2078121) X axis. Endstop lever gets about 10mm to the left of the screw.

Merci, c'est exactement ce que je cherchais :)
