Citroen Xsara Picasso Rear Window Pulley

I printed the rear window regulator pulley for the Citroen Xsara Picasso with supports in PETG, and it has been working daily for more than three months. I have some ideas for making it stronger, but I'd need some photos of break points (if there are any) so that I can strengthen those parts. I have also tried ABS and ASA, both of which were not strong enough, since the pulley needs to have some give, and PETG seems to be perfect.
