Read that page and for people like me (non-coders), I have no idea what to do next. It says add the file path to the script to run (I get that) but in the zip file there are multiple files in the slic3r post script folder. Which is the executable file you link to? Where does the parent folder get placed?

I m happy not using this, just thought it intereesting enough to try and incorporate into my printing routine.
