Have you tried to print such a piece? In my opinion the result won't be good.
It occurred to me only just now that you may have been referring to the Hangman, not the Zip. Indeed, I can see your concern, but I've found that a minimum of 2.5mm can be considered reasonably sturdy in PLA, and the rope is 3mm in diameter if printed full size. (Still, I'd store it carefully, and wouldn't be too rough with it.)
