The Best Gridfinity Generators in 2026 (Free, No CAD)

Gridfinity turned drawer organisation into one of the most printed categories on every model site. The catch is that every drawer is a different size, and every set of tools needs different pockets. That is exactly the job for a generator: you enter the numbers, it gives you parts that fit.

We went through the Gridfinity generators that are alive in 2026 and sorted them by what you are trying to do.

Quick answer

• Best all-rounder: Perplexing Labs Gridfinity Generator. Free, in the browser, no account, and it also does openGrid, Multiboard and honeycomb wall parts.
• Best for planning a whole drawer: Gridfinity Layout Tool. Lay out every bin first, then export.
• Best for odd-sized drawers: Ultimate Gridfinity Drawer Configurator on MakerWorld.
• Best for tool inserts: Tooltrace. Take a photo of your tools on a sheet of paper and get a fitted insert.
• Best for labels: CNC Kitchen Gridfinity Label Generator.

Bins and baseplates in the browser

The Perplexing Labs generator is where most people start, and for good reason. It runs in the browser, needs no account and covers bins, baseplates and several other storage systems in one place. If you only bookmark one Gridfinity tool, make it this one.

GridfinityCreator and Gridfinity Generator cover similar ground. GridfinityCreator is free and exports STEP as well as STL, which helps if you ever want to edit a part later. Gridfinity Generator has an interactive editor with cutouts on a shared grid, and an optional subscription mostly for saving more models.

Planning a whole drawer

Printing bins one at a time works, but you end up with gaps. The Gridfinity Layout Tool flips the process around: you draw the drawer, place bins on the grid until it is full, and then export custom bins and baseplates in one go. It exports STL, 3MF and STEP.

On MakerWorld, the Ultimate Gridfinity Drawer Configurator does something similar from the other direction. You enter your drawer’s inside size, and it produces a fitted grid, bins and lids. Like all MakerWorld customizers, it runs in the browser but needs a free MakerWorld login.

Baseplates that fit your printer

Large drawers need baseplates bigger than most print beds. The Extrabold Gridfinity Baseplate Generator knows about your printer: it splits the baseplate into pieces that fit your bed and join back together. No account, free, STL or 3MF.

Drawers that are not a multiple of 42 mm

Not every drawer plays nicely with a 42 mm grid. The Spacerless Gridfinity Bin Generator makes bins in exact millimetre sizes and odd shapes, so you can fill the leftover space without printing spacers. If you don’t need Gridfinity compatibility at all, the Ultimate Parametric Drawer Organizer makes plain custom-size trays that tile and stack.

Inserts for tools

Tooltrace is the most fun tool on this list. You lay your tools on a sheet of paper, take a photo, and it traces their outlines into a Gridfinity insert or a foam shadowbox. The free plan allows three active traces; Pro costs $8 per month.

Labels

Once you have forty identical bins, you need labels. The CNC Kitchen label generator makes embossed labels with icons and has ready-made sets for screws, nuts and other fasteners. It supports a colour change for contrast.

Tips for printing Gridfinity

• Print baseplates first, and check the fit of one bin before you print twenty.
• Use a 0.4 mm nozzle and 0.2 mm layers for bins. Finer layers only add time.
• Magnets are optional. Many baseplates have pockets for 6 x 2 mm magnets that stop bins sliding around.
• Vase mode makes very light bins quickly, but they are fragile. Use normal walls for tools.

Frequently asked questions

What is Gridfinity?

Gridfinity is a free, open modular storage system designed by Zack Freedman. Bins and baseplates follow a 42 mm grid, so parts from different makers fit together. You print a baseplate for your drawer and drop in bins of any size.

Do I need CAD to make Gridfinity bins?

No. The generators on this page let you type in the number of grid units, the height and the number of compartments, and give you an STL or 3MF. Some even take the size of your drawer and plan the whole layout.

What filament is best for Gridfinity?

Plain PLA is fine for almost all bins and baseplates. Use PETG for bins that hold heavy tools or sit in a warm garage. A matte PLA hides layer lines well on large flat bins.

My drawer is not a multiple of 42 mm. What now?

Use a generator that adds padding to fill the gap, such as the Ultimate Gridfinity Drawer Configurator or the Extrabold baseplate generator, or use spacerless bins that are sized in millimetres instead of grid units.
