This rear wiper blade retainer clip is designed to replace a broken clip on my Skoda Fabia, but it'll probably fit many other wipers from many other cars in the Volkswagen Group (VAG).
I wasn't able to find the plastic piece for cheap anywhere and I didn't want to buy a whole new wiper arm for just a small plastic piece, so I decided to model it and make it myself.
Print it in ABS, PETG, ASA or whatever good and resilient plastic you have. I personally did it in PLA and it's been holding on for a quite a long time already, but ymmv.
Given the platform of the car, there's a chance that all these models also use this clip. List extracted from Wikipedia:A04 (PQ24)
