"Our partner, Prusa Research, is based in the Czech Republic, so we are reaching out to its community to join us. We know that 77% of Europeans would prefer a repair to a new product, but the majority end up buying a new one anyway. Especially Czech consumers have a very positive attitude towards repairs and we are happy to support them." (automated translation)

And this seems to present itself as an official place to dowload the (1 for now) model: https://www.printables.com/@Philips

If they released circuit schematics, etc as well then I'd be impressed.

What that means is that if the original part breaks, the replacement will break too. Even if you just go for equivalent strength, the replacement has to be significantly larger and in many cases is simply not possible (as printed objects are quite weak along layer lines.)

I'm sure there are all sorts of counterexamples people have posted online, but the evidence is out there. Look at thrift stores or eBay or whatever. You can find plenty of objects repaired with traditional methods (epoxy, fillers, metal plates, glues, rivets, screws, plastic welding, etc) but I have never come across any used items repaired with 3D printers.

Perhaps in five or ten years we'll all be printing high strength nylon or continuous fiber parts at home, but for now I'm chalking this one up to marketing.
