Thanks guys. I just took 5 mm of the lenght, it works fine.
I do have a couple of additional questions.
Do these cases have a tendency to curve inwards on the back? Because all of mine do. By the back I mean the side where all the plastic parts are located for holding the games. I hope you get what I mean.

And I have noticed that the covers I print tend to "bobble/crumble" on the middle section of the cases. Perhaps I should use a different kind of paper, rather than standard?
