About MODULITH
Who makes it, what it is, and how to reach the person behind it.
Who
MODULITH is designed and made by Jerrari - Joey Gasper, one designer, working as Jerrari Design. It started in 2019 as a single drawer for one workbench, printed on a used Prusa MK2, and has been designed and photographed at that same bench ever since - the original parts were tested there, and it is still where the work happens. There is no team behind the name: the parts, the Planner, the guides and the videos come from one person, with a Club of members and a community of builders around it.

What it is
A 3D-printable modular storage system. Cases connect on a shared grid with a printed QuickLock, drawers and shelves fill them, and the whole thing mounts on a desk, under a surface, or on a wall. Nothing you print becomes obsolete: every part released since 2022 fits every other, and the newest release fits a case printed in 2022. The How It Works page shows it in ninety seconds; the story tells how it came to be.

How it is made and shared
The files are what is shared: 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 core system is free: cases, drawers, covers, rails, hardware and several faceplate styles download at no cost from Printables, Thangs and MakerWorld, and the Planner lays out a build and lists every file it needs. The Club is what funds the ongoing design work; members get the club faceplate and handle series and a say in what comes next.

Where to see it in person
Builds you can pick up, open and handle, and the designer to talk to.

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
