Where to get good clear plastic case

Hello! I r3cently bought this clear case off of alliexpress to protect my majoras mask cover plates. However, the cases are much too tight and don't sit flush on the console. I used to have hinges but I had to cut them using a godhand, since the bending hinges made the top protection pop off the console when opening. Where can I buy a good clear case for my new 3ds? I'm afraid to order on alliexpress again.
