I have an old CD holder that is built into a cabinet. It is being repurposed to hold MtG decks.

This tray has the width and height of a CD case. The depth fills the cabinet I have and is deeper than a standard CD case.

I printed each mana type with the appropriate color of filament.

The Template file is the card tray with no mana glyphs added.
I have included the DesignSpark mechanical files I used to design each.

A few of the mana symbols, like the water, might require supports on your printer. It printed with no supports just fine on my printer.
