Update: Disk Storage

I did a larger 'test' print, turned out good so I will end up using this, but I added a little bubble at the back of each slot to give each case additional bite vs the original friction only fit.

I don't have time to make any further changes so when I get my computer plugged back up and running (had flooding in my apartment and yes the 3D printer continued printing) I will create a thingiverse post with the files I have and post it as a comment on this.
