Here we are just over a month in with the 3D printed bed wiper.

It seems to be holding up fine, no hot steel bits embedded in it, the porous nature of the PLA print has taken up oil and the bed keeps its meniscus of oil. Some of the really fine stuff gets stuck to the front lip, but no more than I have seen on the felt wiper. I will keep using this one and print another if I damage/wear it, but with the designed in adjustment should give it a long life.
