I have large sausage-like fingers. It's hard for me to manipulate tiny things sometimes.
I love the way PC games are packaged now, in DVD-style cases, but I don't like how multiple disks are stacked on top of each other. It makes it hard for me to grab the top disk without grabbing the whole stack along with it.

I also have a large number of empty CD/DVD cake boxes, filler disks, and foam spacers. I didn't ever throw them away in case I think of something to use them for.

Step 1: Eureka!

I just got through clawing my disks apart to get the one on top. I was looking at my stack of cakeboxes and it dawned on me. Try using a foam spacer in the DVD case. A, hah!

I got some of the spacers out and sorted them by thickness and experimented with a two-CD game in a DVD-style case.

The really thick gray ones were too thick. The really thin white ones were okay, but a little too thin. The cheap closed cell, low density foam ones were just right, as well as the nicer closed cell, high density white ones.

Perfect.

Now on to the games with more than two disks.

Step 2: Multi-disk Cases

Using the thick gray ones would definitely not work here. Using the medium thickness white ones and the cheap foams ones would also not work, unless the spindle was taller. I used the thin spacers between each disk and they worked perfectly. I can easily separate the disks with my finger tips without having to use my nails.

Step 3: Summary

I hate throwing away solid plastic packaging like cakeboxes and the other tidbits that comes with spindled CD/DVD's.

I also dislike fighting with the DVD cases to turn loose of game disks.

I think I found a simple solution to the problem using found materials that everyone has.
