I'd recommend nylon PA12 for the print as you'll have strength and flexibility. Next would be polycarbonate and I wouldn't attempt PLA or ABS.

Printing it was not difficult at all. I posted the instructions along with the model.
I do agree that the stress points are a HUGE factor for this particular part. I plan on reporting how long it lasts given that (a) I did not spend more than a few minutes thinking about the stress and (B) I printed it on PETG. So, it is more of an experiment at this time. I am thinking it will last 6 months at most?
I agree on your material choices. I was simply too lazy to switch out to another filament. I am also curious to know if when the part breaks, it causes the carrier to also break and mangle all the wires that move it, because every time that I have had this problem I have had to replace the clip (broken) and the entire window regulator (wires mangled).
