How It Works

formerly GEN2

MODULITH is a 3D-printable storage system: printed cases that click together into drawer units. Print the sizes you need, click them together, and rearrange later - a part you print today still fits a build you expand next year.

See how it goes together

In a hurry? Start with a proven build or design your own.

A finished MODULITH tabletop build on a wooden desk: black cases and covers with nine orange drawers in mixed widths and heights.

From printed parts to a drawer unit

A Case is the printed structural shell; its opening is a bay. Four moments from the real assembly guide for the 185 Tabletop Kit:

  1. One printed case alone on a dark grid, an open box lying on its back.

    1 Print a Case - the structural shell that makes one storage opening, a bay.

  2. Four cases joined two wide and two high, orange QuickLocks seated in the side walls.

    2 Click cases together with QuickLocks - side by side and stacked. No screws between cases.

  3. The same four cases with covers closed and four orange drawers seated in the bays.

    3 Slide drawers into the bays - or deck a bay as an open shelf instead.

  4. The finished unit: gray faceplates with tan handles on all four drawers.

    4 Finish the front - Decor faceplates and handles finish this version. Classic drawers print their grip in and need neither.

How cases connect

Each case takes a matched Left and Right QuickLock. Slide a case on and the sprung tab clicks into its neighbor; press to release, and the build comes apart the same way it went together - so a layout is never final.

Animation: a QuickLock drops into the top of a lower case's side wall. The case above slides on from behind, shown in x-ray as it presses the tab 3 mm down, and at full seat the spring snaps the tab up into its keyhole.

Where will it live?

The same case system mounts three ways. Choose where yours will live:

A Tabletop Kit standing on a wooden desk, orange drawers, black covers and feet
Tabletop

A freestanding, self-contained unit on its own feet.

Adds foot rails, feet, top covers

 Red drawers hanging under a workbench top on under-table rails
Under-table

Hung beneath a desk, shelf or work surface.

Adds under-table rail, wood screws

 A Wall Mount Lite bracket screwed into a wood-panelled wall beside a stack of labeled drawers
Wall-mounted

Fixed to a wall on a bracket, with rows hanging below.

Depth decides which foundations a build can use - the table below compares them.

Pick a depth - that's a Collection

Cases come in six depths, and a Collection groups the cases and the other depth-sized parts for one depth, named by it in millimeters. Choose by what you want to store; the 185 is the Standard all-rounder most builds start from.

Most builds use one depth throughout. Under-table builds can mix depths, tabletop pairs join with released adapters, and wall builds never mix - the exact rules:

59 59 mm deep · 45 mm inside 115 115 mm deep · 101 mm inside 165 165 mm deep · 151 mm inside 185 185 mm deep · 171 mm inside 240 240 mm deep · 226 mm inside 270 270 mm deep · 256 mm inside front face · all six drawn to one scale
CollectionBest forMounts
59 Ultra-shallow · 45mm inside · cards, bits, screws, small flat parts Under-table · wall (too shallow for feet)
115 Medium · 101mm inside · pens, cables, tape, small parts & tins Tabletop · under-table · wall
165 Mini Edition · 151mm inside · sockets, calipers, small tools, hobby bits Tabletop · under-table · wall
185 Standard · 171mm inside · the versatile all-rounder for everyday gear Tabletop · under-table · wall
240 Deep · 226mm inside · power tools, spray cans, boxed sets, tall bottles Tabletop · under-table · wall
270 Large · 256mm inside · long tools, cordless kits, big spools Tabletop · under-table · wall
Can one build mix depths?

The rule is per mount. Tabletop: Normally one depth; Size Adapter Covers join the released depth pairs. Under-table: Can mix depths - a shallower case hangs beneath a deeper one on Bi-Directional QuickLocks. Wall: One depth throughout, always.

Read any size

Case and drawer names list depth, width and height, in that order. Other parts use only the dimensions that apply.

185 2W-1H

Widths and heights combine freely in one build; depth comes from the Collection.

Now decode one yourself - the menus offer only the sizes each collection really makes, with links to the parts:

185 2W-1H decoded: 185 = collection (depth class) · 2W = 176mm wide · 1H = 56mm installed height

A 2W-1H drawer in the 185 collection holds 159 × 48 × 171 mm inside (W × H × D).

See the 185 Case 2W-1H · Every 185 part

Why does a 1H case print 59 mm tall, not 56?
case above this case 59 56 A 1H case prints 59 mm tall. Its 3 mm dovetail rises into the case above, so it occupies 56 mm of the grid. The grid counts space, not plastic.

What fills a bay

The case sets the outside size. What you fit inside decides how you use the space.

A Classic drawer pulled part-way out of its case: a single printed piece with a grip moulded into its front. Classic drawer

Look at the front: the grip is part of the print.

Prints in one piece and needs neither a faceplate nor a handle. Free.

A Decor drawer pulled part-way out of its case, its open flat front showing, with a separate black faceplate and handle floating just in front of it. Decor drawer

Look at the front: flat, with clips. The faceplate goes there.

Swap the faceplate to change the front without reprinting the drawer.

Faceplate and handle sizing

Faceplates and back covers are sized by width and height, not by collection: a 2W-1H faceplate fits a 2W-1H Decor drawer in any collection from 59 to 270. A back cover fits the open-front Decor drawer; a legacy closed-front drawer takes the plate without one.

Handles share one 44 mm two-hole mount, so any handle fits any faceplate that takes one. Essential and Chevron take a handle; the other series print their grip in.

An open shelf in a build: parts boxes resting on a white shelf insert with a black front lip, drawers in the rows below. Or skip the drawer: shelves

A Shelf Insert replaces the drawer in a bay, and the bay becomes an open shelf. The black rail at its front edge is the optional Shelf Lip, keeping contents in.

Cases, drawers, shelves and the Planner are free. 2 of the 5 faceplate series are free too; the other 3 are Club releases, also sold on their own, that fund the design work.

Where to start

A finished Tabletop Kit standing on a desk. Start with a proven build

Every file listed, the hardware counted, and a guided 3D assembly. The shortest path to a finished thing on your desk.

 A MODULITH build mounted on a wall. Design your own

The Planner lays your build out on your printer's bed and lists every file it needs.

Every part's files, sizes and 3D preview live in the catalog. Building now? Assembly instructions cover all three foundations step by step.
