So the replacement PLA part fared little better. It deformed but didn't crack up over 20 mins or so of constant operation - trying to print another Y motor coupling, of course. The red mark is merely a leftover from me marking the length of the grub screw.

I'll try a piece of Teflon. Hmm, nope, too weak - tap tears out. Teflon & hose clamps holding the grub in place, promising...

Have you tried reinforced pvc? You know, the stuff with braided thread in it (I think the thread is nylon)? You see it in garden hose & some medium-high pressure pipe like on plant sprayers with a separate nozzle.
Teflon, grubs and clamps seem to be working for the moment - some experimentation clearly required.
