Gridfinity is a modular, open-source storage system designed by Zack Freedman for 3D printing. It uses standardized grid units (42mm) to create customizable drawer organizers and storage bins that snap together.

How do I use the Gridfinity Layout Tool?

Simply set your drawer dimensions, then click and drag on the grid to create bins. You can resize bins by dragging their edges, organize them into layers, assign categories with colors, and use the 3D preview to visualize your layout. Export your design to share or use the print list to see what bins to print.

Is the Gridfinity Layout Tool free?

Yes. It's free, doesn't require an account, and works offline as a Progressive Web App.

Can I save my Gridfinity layouts?

Yes, layouts are automatically saved to your browser's local storage. You can also export layouts as shareable links or files to back them up or share with others.

How do I plan a Gridfinity drawer organizer?

Use this Gridfinity Layout Tool to plan your drawer organizer: 1) Measure your drawer in millimeters and divide by 42 to get grid units. 2) Set the drawer dimensions in the tool. 3) Draw bins by clicking and dragging on the grid. 4) Use the print list to see which bin STL files to download and 3D print.

Can I use this for tool drawer organization?

Yes, this Gridfinity layout planner is perfect for organizing tool drawers. You can create custom-sized bins for wrenches, screwdrivers, pliers, and other tools. Use the category feature to color-code different tool types, and the multi-layer support for deep tool chests.

What bin sizes are available in Gridfinity?

Gridfinity bins come in any combination of width and depth from 1x1 to larger sizes. Heights are measured in 7mm increments (1U = 7mm). This tool lets you plan any bin size configuration and shows you exactly what to print. Enable half-bin mode for 0.5 unit precision.

Where can I download Gridfinity STL files?

You can generate custom bin STL files directly with the built-in bin generator — no external downloads needed. For specialized bins, you can also find community STL files on Thangs, Printables, and MakerWorld. Search for 'Gridfinity' followed by the bin dimensions (e.g., 'Gridfinity 2x3').

Can I generate custom Gridfinity STL files?

Yes. The built-in bin generator lets you set dimensions, pick a base style, and add compartments, wall cutouts, or label tabs. Export as STL, STEP, or 3MF. It runs in your browser.

What file formats does the bin generator support?

The generator exports STL (standard 3D printing), STEP (for CAD editing in Fusion 360, FreeCAD, etc.), and 3MF (modern format with color and material support). Most slicers accept all three formats.

Do I need to install software to generate bins?

No. The bin generator runs in your browser. There's nothing to download or install. Works on desktop, tablet, and mobile.

Can I generate custom Gridfinity baseplates?

Yes. The baseplate generator lets you set grid dimensions, add magnet holes, configure edge padding per side, and export as STL, STEP, or 3MF. Large baseplates are automatically split into pieces that fit your print bed.

Do I need magnets for Gridfinity baseplates?

Magnets are optional. They keep bins from sliding but aren't required. The baseplate generator lets you enable or disable 6mm x 2mm magnet holes at each grid intersection.

Is there a free Gridfinity planner?

Yes. The Gridfinity Layout Tool is a free Gridfinity planner that runs entirely in your browser. No account, no installation, works offline as a PWA.

Can I design Gridfinity drawer layouts online?

Yes. The Gridfinity Layout Tool is a free online drawer planner for Gridfinity. Set your drawer dimensions, drag to place bins on the grid, organize with layers and categories, then export a print list with every bin size you need.
