Upgrade your card storage with a modular, interlocking deck box system designed around Magic: The Gathering Commander decks, but can be utilized for any number of games and card combinations — brought to you by OpenForm Creations.

This isn’t just a deck box — it’s a buildable storage system. Each box securely holds a full Commander deck and connects to other boxes to form a larger, organized structure. Bring one deck or bring your whole arsenal — no bag required.  Part of a growing modular deck storage system — expand anytime with handles, straps, playmat holder, and custom lids.

The built-in interlocking design allows multiple boxes to attach together for easy transport, and the system can be configured to support handle or strap attachments when carrying several decks at once.

Perfect for Commander nights, tournaments, or keeping your collection neatly organized at home.

Designed for easy 3D printing, this model prints without supports and features a reliable snap-fit lid to keep your cards protected.

Future expansion is part of the system — custom lids, attachments, and alternate box styles will be released so you can personalize your setup over time. This is a growing modular ecosystem from OpenForm Creations, built for players who want smarter storage.
