I came across this ages ago with stumbleupon and thought I'd share it; Paper Cd Cases
. I love origami and since coming across this I've haven't used anything else since for holding the multitude of cds I burn
Now personally I don't bother with creating a printed page from the site, nor do I follow the steps as they're described in the PDF. I simply place a cd on an A4 page to judge the width needed to form the two initial length-wise folds which gets you to step 1 (thats step 1 in the photos, not pdf) everything after that is easily judged, no real guides are needed as the design is very tolerant.
