Oh, did you mean something like that? I thought you were looking for a carrying case.
I think I'm going to buy this one:
http://www.amazon.com/Nintendo-3DS-H.../dp/B004K6LQ7G
It's made by Hori (excellent company) and has an official Nintendo seal. It can hold 3 games which is great and hold an extra stylus. It looks like it will really protect the 3DS, too.
