Do you have a case for your 3DS or other handheld consoles?
I used to have one for my original Nintendo DS, but sold it as I never used it. I also had one for my Gameboy Advance, but it was mainly for storing games, and just had a little space to fit the GBA in it.
I don't have one that I actually use though. It's probably better to get a case for the 3DS because they're more like protectors rather than just a case so you don't have to carry around the console.
