This seems like a stupid question, but due to taking the SD out a lot and having to keep unscrewing/screwing those tiny screws, I've basically stripped the poor little screws on my N3DS XL. I could buy a replacement battery cover, but those are a bit expensive and I'd just have the same problem again. Does anyone know where to get the same type of tiny screw in bulk so I can just buy a bag of them? They're too small for the local hardware store to have any. But I know sometimes people on eBay have them - I've found the proprietary tiny screws for laptops and such, does anyone know what this size screw is called?
