MODULITH 185 Under-Table Starter Kit

Turn the underside of any table into storage.

Screw in a rail, slide in a drawer. MODULITH rails mount under a desk, shelf or enclosure table with a few wood screws. Cases slide on and QuickLock holds them, so you can swap or rearrange drawers in seconds.

Everything for a first setup. Rails from 1W to 4W, 1W-1H and 2W-1H cases, both drawer styles, Classic Faceplates, Side Covers and the hardware to tie it all together.

Pick your drawer style. Classic drawers have a print-in-place handle. Decor drawers take swappable faceplates and handles, so you can change the look anytime.

Grow it whenever. Every 185 drawer, insert and faceplate fits the same rails, so this kit is just the beginning.

GEN2 is now MODULITH. Same system, same compatibility. Print only what you need, snap it together with QuickLock, and rearrange or expand your storage anytime.

PICK YOUR BUILD

WHAT'S IN THE DOWNLOAD

• Rails: 185-1W and 2W (the best fit for most printers), 3W and 4W. The 2W-2H build uses a 2W rail and the 3W-2H a 2W and a 1W, butted edge to edge, so neither build needs a rail wider than a 2W

• Cases: 185-1W-1H and 185-2W-1H (v2602)

• Drawers: 1W-1H and 2W-1H in both Classic (v2508) and Decor (v2609). Decor drawers print with a tear-away front: snap it off, or leave it in unless you add a faceplate back cover. The older Decor files (v2602) stay on this page, marked (LEGACY)

• Classic Faceplates: 1W-1H and 2W-1H, each as an STL and a ready-to-slice multi-material 3MF

• Side Covers: 185-1H as an STL and a two-material 3MF, an optional finish for the end walls

• Hardware: QuickLocks (print in PETG), Bi-Directional QuickLock for hanging shorter drawers under longer ones, optional drawer stoppers, 6x2mm and 10x2mm magnet inserts

WANT A DIFFERENT FRONT?

The Classic Faceplates in this download are free. Every faceplate series of the same size fits the same Decor drawer, so you can change the look later without reprinting the drawer.

• EdgeLabel: snap-on faces with swappable printable labels. Easy multicolor, even on a single-color printer.

• Classic Pro: the classic look, with swappable labels and accents.

• Chevron: a 45 degree pattern that lines up across every drawer. Takes a separate bolt-on handle and M3 screws.

These three are paid models, each on its own page, and included with the Jerrari Club.

WHAT YOU PRINT

Quantities are prints, not parts. QuickLocks and Drawer Stoppers each come as a left/right pair on one plate, so one print gives you both pieces.

WHAT YOU'LL NEED

• Wood screws: 6 for the 2W-2H, 10 for the 3W-2H. Countersunk #6 × 3/4 inch (3.5 × 19 mm) is the default. That screw reaches about 16 mm into the top, so check the top is thick enough and choose a length that cannot break through.

• Tools: a screwdriver, a drill bit smaller than your screws, and a pen, marker or scratch awl to mark the holes.

• Filament: PLA or PETG.

• Magnets (optional): 6 or 10, 10×2mm or 6×2mm, only if you add the magnetic closure.

• M3 nuts and screws for some faceplates and handles: stainless steel or steel
