I'm in a strange situation now. A friend came over a couple days ago and used my 3DS XL which I normally do not let anyone touch. Well, the circle pad is now badly scratched up and, while it still moves fine, feels rough under my thumb. I have a huge phobia of wear and tear in general, and I have this irresistible urge to replace it. I can find literally every single replacement part on-line EXCEPT for the circle pad cap. I am also willing to buy full replacement housing packages as long as they include a circle pad cap. Does anyone know where I can get one, and why they're so hard to find for some ordinary piece of rubber? Please help. Thanks in advance.
