This is a simple rack for DVDs, games, CDs, and the like. It is pretty heavily parametrically customizable: you can have up to four sections, each with a different compartment width (e.g., some for normal size DVD cases and some for CD jewel cases).
It is intended for the long side to be down in use, but to print with a shorter side down. But you can also use it with short side down.
You can glue multiple segments together (I used ABS juice) if you need a longer setup than will fit in your printer.
