A practical Commander deckbox – with a locking sliding lid and stackable body.

This deckbox is built specifically for Magic: The Gathering Commander/EDH players who want to keep their main deck, commander, and sideboard/tokens organised in one compact box. The sliding lid locks securely into place, preventing accidental openings during transport.

Key features:

• Locking sliding lid – Slides smoothly and clicks shut. No magnets or additional hardware required.

• Three internal compartments:

  • Main deck slot – fits 100+ double-sleeved cards

  • Commander slot – separate recess for your face card

  • Sideboard / tokens slot – extra space for a few sideboard cards or tokens.

• Stackable design – The flat top and bottom allow multiple deckboxes to be stacked securely. Perfect for carrying several decks or storing them on a shelf.

• Easy to print – No supports needed (depending on orientation; print lid upside down). Uses minimal filament.
