Modi Case: The 3D Printable Case Building System

 
Modi Case is built to handle just about every part of your tabletop hobby in one unified system. You can use it to organize and transport miniatures safely, store and sort trading cards or deck builds, and even create a fully functional D&D setup with integrated screens, dice trays, and tools for running sessions. 

It works just as well for general game storage, letting you break down bulky boxed games into efficient, portable modules, or for hobby setups like paints, brushes, and tools, so you can bring your entire workstation anywhere. 

Modi Boxi has evolved over the past two years through constant feedback, iteration, and real-world use. Every improvement has come from listening to our builders and refining the design. Modi Case continues that approach, complementing the existing system and extending it in ways that feel familiar and intuitive.

All Modi Boxi packs are available as add-ons for this campaign. For more info, you can check out https://modiboxi.com. The available add-ons are:

Modi Case gives your miniatures a smarter, safer home. Instead of foam trays or loose bins, you get infinitely expandable modular storage that keeps your figures organized, visible, and protected. Customizable trays and racks let you separate by army, campaign, or build, while Modi Loops, Rails, or trays keep everything in place during transport. Open your case, and your minis are ready for the table. 

Modi Case makes it easy to organize, protect, and transport your cards with a system built for flexibility. Whether you’re managing sleeved decks, sorting by set, or keeping multiple formats ready to play, you can configure layouts that match exactly how you use your collection. 

With Modi Case, you can build powerful DM command centers filled with everything you need to run your sessions. Build a customizable screen setup with panels, note holders, dice trays, rollers, and matt or mini storage, all integrated into one case. Keep your notes hidden, your essentials organized, and your workflow smooth behind the screen—then pack it all up instantly when the session ends. It’s a cleaner, more portable way to run immersive DnD sessions without the clutter.

 

Board games are amazing—but their packaging usually isn’t. Once you unpack everything for the first time, it never goes back the same way. Or maybe you are playing a 3D printable board game or RPG that never came with packaging in the first place!  

Modi Case lets you design storage for your favorite games from the ground up, creating clean, modular layouts that actually fit how you play. Organize tokens, cards, and components into purpose-built trays so everything is easy to find, quick to set up, and just as fast to pack away. 

Paint supplies grow fast—and most storage options don’t keep up. Modi Case lets you build a paint storage system that works for how you paint, with modular racks and holders that keep bottles visible, organized, and within reach. 

Do you want to put board game boxes inside your BOXIS!? Well, we have you covered. Put all your board games in a giant Modi Case and take it anywhere you want to go, or use it for storage at home. With Modi Case, you can print some truly large designs that can store almost anything. 

 

The Modi Case × Amsel Suite collaboration is all about connecting how you plan your game with how you play it at the table. Amsel Suite acts as the digital “grimoire,” where you build your worlds, track your campaigns, and organize your story, while Modi Case becomes the physical “bag of holding” that carries everything you need to run it—your minis, dice, maps, notes, and tools.

Together, they create a seamless workflow for game masters: design and manage your adventure digitally, then bring it to life with a modular, portable setup that keeps everything organized and ready to go.

Back their campaign alongside ours and unlock a Modi Foldable Laptop Stand and a special sound library for the Amsel Suite Harp product! 

• Modi Case comes with a full set of instruction and print lists for over 6 starter configuration. From there let your imagination run wild.

• Modi Case comes with pre setup .3mf files for the 2x style cases. Just open and start printing. 

Jeff and Trapper are the creators behind Modi Boxi, one of the most successful 3D printable STL Kickstarters, backed by thousands of hobbyists who wanted a better way to organize their games. Modi Boxi proved that modular, customizable storage could replace rigid, one-size-fits-all solutions—and the community pushed it even further with creative builds and new use cases.

But as people used it, one thing became clear: storage was only part of the problem. Gamers wanted something more portable, more integrated, and better suited for actually bringing their setups to the table. That’s why we created Modi Case. It builds on everything we learned from Modi Boxi and takes it to the next level—combining storage, transport, and active gameplay into one modular system designed for how people really play.
