About MODULITH
I'm Joey. I use Jerrari online, and the work goes out as Jerrari Design.
It began in 2019 as a single drawer, printed on a used Prusa MK2 for a new 3D-printing hobby. There is still no team behind the name: one person makes the parts, the Planner, the guides and the videos. A lot of what makes the system good came from the people around me, though: builders and Club supporters suggesting, testing and feeding me ideas. I design and test it on several workbenches, walls and tabletops.
How to reach me about a build, a press request or a problem.
What it is
MODULITH, formerly GEN2, is the 3D-printable modular storage system. The name is MODU + LITH - many modules, one system.
Cases connect on a shared grid with a printed QuickLock, drawers and shelves fill them, and the whole thing sits on a desk as a tabletop kit, hangs under a surface, or mounts on a wall. What you print keeps fitting: the case grid and the mounting architecture have not changed since GEN2 began in 2022, so a drawer printed now slides into a case printed then. Parts are sized by collection, and a collection is a case depth, so a build picks one collection and matching sizes within it; the universal parts are shared across collections: faceplates in their matching width and height, handles, QuickLocks and hardware outright.
How It Works shows how it fits together; the story tells how it came to be.
What's free, and what pays for it
The files
Cases, drawers, covers, rails, hardware and several faceplate styles download at no cost from Printables, Thangs and MakerWorld. The Planner lays out a build and lists every file it needs.
The prints
Print it yourself, on your own printer, in your own colors, or buy prints from one of the makers who print and sell MODULITH parts.
The Club
The Club funds the ongoing design work. Members get the club faceplate and handle series and a say in what comes next.
Five milestones

- Summer 2019
The first drawerA single, non-modular drawer, designed as personal storage for a new 3D-printing hobby on a used Prusa MK2.
- June 2022
GEN2 is bornThe system is reimagined around a modular case and mounting architecture. The system-wide compatibility promise begins here.
Still the architecture today - March 2024
QuickLockThe QuickLock mechanism lands: storage that swaps around in seconds rather than minutes.
Still in the system: QuickLock - November 2025
Cubby ShelfThe system expands beyond drawers into open storage.

Contact
Questions, ideas, or something you would like to share? Your email comes straight to me.
- Share your build. Send a few photos, what you use it for, and whether I can show it on In the Wild with your name or handle.
- Press and collaborations. Working on a video, an article or a project involving MODULITH? Tell me what you have in mind.
- Help with a part or a file. Comment on the model's page, so the answer can help other builders; the part's page in the catalog links to it.
- Planner or website issue. Email what happened, the page or the build's Share link, and a screenshot if you can.
For a quick word, a message on X or a comment on YouTube also reaches me.
New parts and builds show up on X and YouTube, everything printable lives in the catalog, and what is new on this site is always at the top of the homepage.
See it in person
At a show you can pick up the builds, open them and talk to me.
No shows on the calendar right now. The next one will be announced here and at the top of the site.
