From One Campaign to Many: How Modi Boxi Can Expand With Your D&D Collection

A D&D collection rarely stays the same for long. One campaign can start with a small group of adventurers and a few monsters, then grow to include more miniatures, dice, cards, tokens, and accessories. Before long, a storage setup that once worked perfectly can become difficult to manage.

Modi Boxi takes a modular approach to tabletop storage, using 3D-printable components that can be built, assembled, and expanded as your collection changes. This guide explores how Modi Boxi can support a D&D collection as it grows from one campaign into multiple adventures.

Why Growing D&D Collections Need Flexible Storage

Traditional miniature cases and organizers can be useful when a collection has predictable storage needs. Foam cases, for example, offer ready-made compartments that make it easy to store and transport miniatures without setting up a system yourself.

The challenge comes when the collection starts changing. New miniatures can have different shapes and sizes, while each campaign may require its own mix of characters, creatures, cards, tokens, and accessories. Adding another fixed case can solve the immediate problem, but it can also mean managing several separate storage systems over time.

A modular setup takes a different approach. Instead of treating storage as a finished product, it allows players to build around what they currently have and add to the system when their needs change.

That approach suits D&D particularly well. A single collection can include miniatures, dice, spell cards, condition tokens, and other tabletop accessories. 

Modi Boxi is designed around this broader RPG use case, with storage options for miniatures, dice, cards, tokens, and accessories. Its modular components can also be stacked and connected to create a customized setup.

Modular D&D Miniature Storage for Growing Campaigns

The biggest advantage of modular storage is its ability to develop alongside a collection.

A player might begin with a smaller setup for a new campaign. As the campaign introduces more characters, monsters, and accessories, additional storage can be printed and added to the existing system. When that campaign ends, the same components can continue to be used for another adventure or tabletop game.

This makes modularity useful for players who do not want to replace their entire storage setup whenever their collection changes.

For anyone searching for the best 3D printable storage solution for a growing D&D collection, flexibility is an important consideration. Modi Boxi is not limited to one type of tabletop component. Its D&D storage range is designed for miniatures, dice, cards, tokens, and accessories, while the wider system also supports other tabletop gaming needs.

Starting With Modi Boxi Core for D&D Storage

Modi Boxi Core provides a starting point for building a modular storage system. It works with FDM 3D printers with a bed size of at least 180mm, with a 250 × 250mm print bed recommended. The Core includes more than 850 STL files ready to print without supports.

The system also uses the patented Modi Bolt and is designed so players can build and customize their storage as their collections grow. This gives D&D players a way to start with the components they need instead of trying to plan an entire storage setup at once.

For larger storage requirements, Modi Boxi XL offers a larger format designed for high-capacity builds.

Expanding D&D Storage With Modi Boxi XL and Pro Packs

As a D&D collection expands, players may need more space or additional functionality. Modi Boxi XL is designed for larger builds and recommends a 250 × 250mm or 300 × 300mm print bed. It includes more than 750 STL files and provides a larger storage format.

The Pro Packs offer another way to expand an existing Core or XL setup.

• Pro Pack 1 requires the Core or XL and adds more than 150 STLs. Its features include paint holders and drawers, an under-table mount, Pro Flat arms, vertical card holders, card drawers, DIY trays, support walls, and sidecars.
• Pro Pack 2 also requires the Core or XL and adds more than 650 STLs. It includes the Swivel System, Half Boxis, and half drawers for smaller printers.

For D&D players, these additions make the system useful beyond basic miniature storage. The same setup can accommodate different parts of a gaming and hobby workspace as the collection develops.

Modi Boxi vs. Traditional D&D Storage Cases

Traditional foam cases have one clear advantage: convenience. They come ready to use, so players do not need a 3D printer or time to produce the storage components.

A 3D-printable system requires a different process. Players need access to a suitable printer, download the STL files, prepare them in a slicer, print the pieces, and assemble the finished components. Modi Boxi's process is built around downloading the files, preparing the prints, and assembling the pieces without tools.

The tradeoff is greater control over how the storage system develops. Instead of purchasing another complete case when the collection changes, players can print additional components for their existing setup.

That makes Modi Boxi especially relevant to D&D players who already own an FDM printer and want their storage to be part of a customizable tabletop setup.

Building a Storage Solution for Minis in 2026

D&D storage has evolved beyond simply finding a box for miniatures. A growing collection can involve characters, monsters, dice, cards, tokens, paints, and other hobby equipment.

This broader approach is one reason modular systems can be useful for tabletop players. Modi Boxi is designed for D&D and other tabletop RPGs, while the wider system also has storage applications for board games, Warhammer, and trading card games.

For players comparing the best storage solution for D&D, Warhammer, and tabletop games, the right choice depends on how they prefer to manage their collections. A traditional case can be practical for someone who wants an immediate, ready-made option. A modular 3D-printable system may be more appealing to someone who wants to build and adjust storage over time.

A D&D Storage System That Can Grow With Your Collection

A good D&D storage setup should work for the collection you have today while leaving room for the campaigns you have yet to play. That is where a modular approach can make sense.

Modi Boxi lets players start with a Core or XL foundation, print the components they need, and expand the system with additional modules and Pro Packs. For D&D players with an FDM printer, this creates an alternative to repeatedly replacing fixed storage as their collection grows.
