Gridfinity Tool Drawer Organizer

Plan a Gridfinity layout for your tool drawer, toolbox, or rolling chest in your browser. Drag bins onto a grid sized to your drawer, generate custom bins for the tools that need fitted slots, and get a print list of everything you need — free, no account.

Why Gridfinity Works for Tool Storage

Tool drawers collect chaos because every tool is a different size. Gridfinity solves this with a standard 42 mm grid: every bin, no matter its footprint, clicks into the same baseplate. When your tools change, you reprint one bin instead of redesigning the drawer.

Bins stay put. The baseplate's raised grid holds bins in place when the drawer slams shut. Add magnets for rolling tool chests.
Every size you need. From 1×1 bins for hex bits to long 1×6 trays for files and wrenches — and half-bin sizes for drawers that don't divide evenly by 42 mm.
Reconfigure anytime. Lift a bin out, move it, drop it back in. The grid keeps everything aligned.

Plan Before You Print

A drawer full of tools is a lot of filament. Planning the whole layout first means every bin fits on the first try:

Measure the drawer — interior width, depth, and height in millimeters. The calculator converts measurements to grid units.
Lay out the bins — drag to place bins in the planner, sized to each tool group. Use categories to color-code: drivers, sockets, measuring, cutting.
Check the fit in 3D — the isometric preview shows bin heights so you can confirm everything clears the drawer above.
Print from the list — the print list shows every bin size with filament estimates, so you can batch bins by plate.

Deep tool chest drawers can hold stacked layers. The planner supports up to 10 layers per drawer, with bins that stack on each other's lids.

Fitted Slots for Bits, Sockets, and Odd Tools

Generic bins handle most tools, but some deserve fitted storage. The bin generator builds these in your browser:

Hex floor cutouts hold screwdriver bits and driver inserts upright in a grid.
Circle cutouts fit sockets, batteries, and collets — set the diameter per row.
Slot cutouts hold blades, wrenches, and feeler gauges on edge.
The pen tool draws freeform outlines for pliers, snips, or anything with an odd profile — the bin prints with a fitted cavity.
Label tabs keep every bin identified, with bracket or solid supports.

Works With Your Tool Chest

Gridfinity baseplates can be sized to any drawer that fits a 42 mm grid — workshop benches, kitchen tool drawers, Husky and Milwaukee chests, IKEA Alex units, or a Packout drawer in the van. Measure the interior, generate a baseplate with per-side edge padding to absorb the leftover millimeters, and the planner handles the rest.

Frequently Asked Questions

What size Gridfinity bins fit a tool drawer?

Divide the drawer's interior width and depth in millimeters by 42 to get the grid size. A typical 570 × 420 mm tool chest drawer fits a 13 × 10 grid. The layout planner computes this automatically and shows the leftover space, and half-bin mode handles drawers that don't divide evenly.

Will Gridfinity bins slide around in a rolling tool chest?

Bins clip into the baseplate's raised grid profile, which keeps them in place when the drawer opens and closes. For rolling chests and heavy use, print bins with the magnet base style and add 6mm × 2mm magnets for extra hold.

How do I make bins for specific tools like wrenches or pliers?

The bin designer's cutout editor has a pen tool for drawing freeform shapes, plus ready-made hex, slot, and circle floor cutouts for bit sets, sockets, and batteries. Draw the tool's outline, set the depth, and the bin prints with a fitted cavity.

How tall should tool drawer bins be?

Measure the drawer's interior height, subtract about 5 mm for the baseplate, and divide by 7 to get the maximum height in Gridfinity units. A 70 mm deep drawer fits 9U bins. Shallow drawers usually work best with 2U or 3U bins.

Do I need a baseplate in every drawer?

A baseplate keeps bins aligned and stops them sliding, so it's recommended for tool drawers. The baseplate generator sizes one to your drawer, adds optional magnet holes, and splits large plates to fit your print bed.
