What do you use most with your 3DS. It can be made for 3DS specifically or another system, or have nothing to do with it. Be it a charging cradle, carrying case, skin, stylus, battery pack, headphones, some other peripheral, or you name it. Whats your goto accessories? My two faves are my FiiO E11, ATH-M50x, and 3DS USB charge cable granting my 3DS power access to my power banks.
