A growing Warhammer army is exciting until you run out of places to put it. More miniatures mean more trays, paints, dice, accessories, and oddly shaped models that do not always fit neatly into standard storage.
Modi Boxi offers a 3D-printable, modular approach to miniature storage that can be built around the collection you already have and expanded as it grows. This guide looks at how Modi Boxi works, how its Core and XL systems fit different storage needs, and why modular storage can be useful for Warhammer, D&D, painting, and other tabletop hobbies.
Why Growing Warhammer Armies Need Flexible Storage
Miniature collections rarely stay the same size for long. A player may start with a small force and gradually add infantry, larger models, vehicles, paints, dice, cards, and other gaming supplies.
Fixed storage can work well when the collection is predictable. The problem comes when the contents change. A tray designed around one set of models may leave unused space in some areas while failing to accommodate larger or differently shaped miniatures elsewhere.
Modular storage takes a different approach. Instead of committing the entire collection to one fixed layout, you can build around the models and equipment you actually need to store. That makes flexibility particularly useful for Warhammer players with armies that continue to expand.
How Modi Boxi Works as a 3D Printable Storage System
Modi Boxi is built around downloadable STL files that can be prepared in a slicer and printed with an FDM 3D printer. The system follows a simple three-step process: download the files, design your build, then print and assemble the pieces. The components snap together without tools, creating a modular setup for gaming and hobby gear.
The system is designed to let users create storage layouts rather than rely on one predetermined configuration. That can be useful when an army contains models with different sizes or when storage needs extend beyond miniatures.
The dedicated Warhammer storage range also highlights adjustable tray depths and modular components for organizing everything from infantry to larger vehicles.
For hobbyists who already own an FDM printer, this approach can turn the printer into part of the storage process rather than requiring every new storage need to be solved with another physical organizer.
Modi Boxi Core and XL for Growing Miniature Collections
The Modi Boxi Core is positioned as the starting point for the system. It currently includes more than 850 STL files and works with FDM 3D printers with a bed size of at least 180 × 180 mm. A 250 × 250 mm print bed is recommended.
The Modi Boxi XL provides a larger format for hobbyists who need more storage capacity. It includes more than 750 STL files, supports most files on a minimum 180 × 180 mm print bed, and has recommended print bed sizes of 250 × 250 mm or 300 × 300 mm.
This gives Warhammer players two starting points depending on their available printer and preferred storage scale. The important part is that neither option has to be treated as a final configuration. The modular design allows storage to develop alongside the collection.
Modular Storage for Miniatures, Paints, and Gaming Gear
Warhammer storage rarely means miniatures alone. A typical hobby setup may also need space for paints, dice, cards, tools, and other accessories.
Modi Boxi is designed around that broader use. The system can accommodate miniatures as well as paints, dice, cards, and other gaming supplies. This is where the modular approach becomes particularly useful. A player can organize miniatures in one part of the setup and use other components for hobby supplies.
Pro Pack 1 expands the system with more than 150 STL files, including paint holders and drawers for different sizes. It also includes an under-table mounting option and Pro Flat arms for bringing Boxis closer together.
Meanwhile, Pro Pack 2 adds more than 650 STL files, along with the Swivel System, Half Boxis, and half drawers designed for smaller printers.
Together, these options make Modi Boxi relevant as a modular storage solution for miniatures, paint, and tabletop gaming equipment, rather than simply another miniature case.
3D Printable Storage vs. Fixed Miniature Organizers
Traditional foam cases and fixed organizers have an obvious advantage: they are ready to use. You select a case or tray, place your miniatures inside, and start organizing.
The trade-off is that the storage layout is already determined. A 3D-printable system changes that relationship. You can select the files you need, print the components, and build a setup around your collection. When your storage requirements change, the modular system can be expanded instead of requiring an entirely different approach.
However, that does not make 3D printable storage the right choice for every hobbyist. It requires access to a compatible 3D printer and involves the additional step of printing the components.
For someone who enjoys customization or already owns an FDM printer, however, that extra step can be worthwhile. Modi Boxi is particularly suited to hobbyists who want more control over how their storage is configured and expanded.
A Flexible Storage Solution for Warhammer and D&D
The same storage problem appears across different tabletop games. D&D players may have collections of miniatures, monsters, dice, cards, and accessories. Board game players may need organized spaces for cards and components. Painters may need dedicated areas for paints and tools.
Modi Boxi is designed to accommodate these broader tabletop needs, with the system extending beyond miniature storage into paint racks, hobby stations, and other modular setups.
That versatility makes it possible to build a storage setup around more than one hobby. A Warhammer player can organize an army while also creating space for paints and dice. A D&D player can use the same modular approach for miniatures and gaming accessories.
Choosing a Modi Boxi Setup for Your Hobby
The right setup depends on what you need to store and the printer you have available. Consider these factors before choosing your starting point:
- Collection size: A growing army may benefit from a larger or expandable setup rather than a fixed organizer.
- Printer size: Check your printer's build area before selecting Core, XL, or individual components.
- Hobby gear: If you also need paint, dice, cards, or tools, consider whether expansions such as Pro Pack 1 or Pro Pack 2 fit your setup.
- Future growth: Think about what you are likely to add to your collection instead of designing storage only around what you own today.
Why Modular Storage Makes Sense for Growing Collections
The biggest advantage of modular storage is that it does not require you to predict exactly what your hobby will look like months from now.
Your Warhammer army may grow. Your paint collection may expand. You may start another tabletop game or need additional space for dice and accessories. A fixed organizer can eventually become a limitation, while a modular system gives you a way to keep building around those changes.
That is the central appeal of Modi Boxi. Instead of treating storage as a one-time purchase, it treats it as a system that can develop alongside your hobby.
For players looking for the best miniature storage in 2026, particularly those interested in 3D printing, modular storage offers a practical alternative to fixed layouts. Modi Boxi Core and XL provide starting points, while Pro Pack expansions add more ways to organize paints, tools, accessories, and other tabletop gear.
A Storage System That Can Grow With Your Army
A growing Warhammer collection needs more than a place to put miniatures. It needs storage that can accommodate different model sizes, hobby supplies, and future additions without forcing the entire setup to be replaced.
Modi Boxi takes a flexible approach by combining downloadable STL files, FDM 3D printing, tool-free assembly, and modular expansion. The Core and XL systems provide different starting points, while Pro Pack 1 and Pro Pack 2 add more options for paints, drawers, mounting, and modular access.
For hobbyists who already have an FDM printer and want greater control over their setup, Modi Boxi can be a practical 3D-printable storage solution for Warhammer, D&D, miniature painting, and tabletop games.
