Rear windshield wiper arm extractor (Opel Corsa D)

I have included two versions of the file. The topology optimized version(chamfered) might drip a bit during printing(depending on your printer), but will work fine and will save material and print time. Both versions can be printed without any supports. If your wiper arm is seized no extractor will probably get it out and you might need to cut it with a saw. In any case, before trying to release it, some penetrating fluid will probably help with the extraction. For the assembly you will need: -M8 nut -M8x25 bolt
