EnglishWhat Is gridfinity.xyz?
Updated
gridfinity.xyz is an unofficial wiki for Gridfinity, the modular open-source grid storage system. It is a resource hub rather than a store: it collects online generators, layout planners, and code libraries for building Gridfinity-compatible parts, and it documents the system's origins and licensing. If you want to design or print Gridfinity bins, baseplates, or organizers, this site is a starting point for both makers and developers.
What Gridfinity actually is
Gridfinity is a modular storage system built around a simple unit: 42 x 42 x 7 mm. As the site puts it, "the best things in life are integer multiples of 42x42x7mm." Parts are designed on that grid so bins, baseplates, and accessories from different sources fit together.
The site describes it as a possible "ultimate modular workshop storage system" that is free, open source, and almost 100% 3D printable. That combination — a fixed grid plus open licensing — is why so many independent tools and libraries exist around it.
What you'll find on the site
The wiki organizes its links by how you want to work.
Online generators (no coding)
| Tool | What it does |
|---|---|
| Perplexing Labs' Gridfinity Generator | Generate custom bins, baseplates, lids, and more by entering your dimensions |
| gridfinitygenerator.com | Design bins and baseplates |
| GridfinityCreator | Generate STL or STEP files for several types of customizable components |
| Extrabold.tools | A full-featured baseplate generator with real-time previews and printer-aware STL output |
| tooltrace.ai | A free custom-holder generator that traces a photo of your tool on A4 or letter paper |
| Gridfinity Layout Tool | A visual drawer planner with multi-layer support, drag-and-drop placement, 3D preview, and print optimization |
The layout tool is worth noting separately from the generators: it plans where bins go in a drawer before you print anything, which avoids printing parts that don't fit your actual space.
Code libraries (for developers)
If you'd rather generate parts programmatically, the site points to libraries across three CAD frameworks:
- Build123d —
PaulBone/gfthings,Ruudjhuu/gridfinity_build123d,moritzmhmk/gridfinity-build123d - CadQuery —
kmeisthax/gridfinity-cadquery(a port of Zach Freedman's system),michaelgale/cq-gridfinity(parameterized components like baseplates and boxes) - OpenSCAD —
vector76/gridfinity_openscad,ostat/gridfinity_extended_openscad(reproduces the original bins with extra customization),kennetek/gridfinity-rebuilt-openscad(a ground-up port with extra features)
Origins and licensing
Gridfinity was created by Zack Freedman and first released in the video "Gridfinity: Your Ultimate Modular Workshop is FREE!" as a framework for the community to extend, under the MIT license. The site also notes that Alexandre Chappel's Assortment System, licensed CC-BY-NC-SA, partly inspired the initial designs.
The MIT license matters practically: it's why so many people can publish their own generators and ports without asking permission, and why the ecosystem on this wiki exists at all.
When this site is useful — and when it isn't
Use it if you want a single index of Gridfinity tools, you're choosing between generators or CAD libraries, or you want to understand the system's licensing before building on it.
Look elsewhere if you want to buy finished Gridfinity products — the site collects design tools, not merchandise — or you need official specifications from the original creator rather than a community wiki.
One caveat to keep in mind: because this is an unofficial wiki, treat it as a curated directory. The tools it links to are maintained by separate individuals, so check each project's own repository for current status and documentation.
