I couldn't bear to put all those jewel cases in a landfill so I made some adjustments to WilliamAAdams quadcorner so the torsion box could be placed upright as storage. I used mine to organize spices. The wood panel pdf is for the labels inside the jewel case. I used the buttons from an old remote as feet to keep the storage case from sliding around.
The storage isn't particularly sturdy, well, honestly jewel cases did a poor job of protecting CDs & DVDs anyway, right? The assembled unit does a good job for small, light items.
Use duct tape or glue to secure each panel into the joints.
