These are separators / dividers I designed with the Magic the Gathering (MTG) mana colors for the Trading Card Organiser box by Mriamsosmrt. The separators make it a modular storage box where you can put in however many cards you have of each type. Extra separators can be stored at the front and back of the box. Each plate in the .3mf file is a divider with its own mana color type.

They look great when printing them out with different color filaments to match the mana types!
