Which Online Gridfinity Generators Are Listed on gridfinity.xyz?

gridfinity.xyz lists five online generators for creating Gridfinity components, each targeting a different job: Perplexing Labs' Gridfinity Generator for dimension-driven bins, baseplates, and lids; gridfinitygenerator.com and GridfinityCreator for STL or STEP output of customizable parts; Extrabold.tools for fast, printer-aware baseplate generation with real-time previews; tooltrace.ai for turning a photo of a tool into a custom holder; and the Gridfinity Layout Tool for planning drawer layouts before you print anything. Pick based on what you need to produce — a standard part, a traced custom holder, or a layout plan.

The five generators at a glance

Choosing by task

If you want standard bins, baseplates, or lids

Start with Perplexing Labs' Gridfinity Generator — the wiki describes it as generating custom bins, baseplates, lids, and more by inputting your dimensions. gridfinitygenerator.com is listed for designing bins and baseplates, and GridfinityCreator produces STL or STEP files for several types of customizable components. If you need an editable STEP file rather than a print-ready mesh, GridfinityCreator is the one to check first.

If you mainly print baseplates

Extrabold.tools is described as a modern, fast, full-featured baseplate generator focused on ease of use, real-time previews, and printer-aware STL generation. The real-time preview matters here: you can see the plate before committing to a print.

If you need a holder for a specific tool

tooltrace.ai is a free custom-holder generator that works by tracing a photo of your tool on a piece of A4 or letter paper. This is the option to use when no standard bin fits the object.

If you want to plan the drawer before printing

The Gridfinity Layout Tool is a visual drawer layout planner for deciding where bins go before you print them. It supports multi-layer layouts, drag-and-drop placement, 3D preview, and print optimization.

If you'd rather generate parts from code

The wiki also points developers to scriptable libraries, which suit repeatable or parametric generation better than a web form:

• Build123d — PaulBone/gfthings, Ruudjhuu/gridfinity_build123d, and moritzmhmk/gridfinity-build123d
• CadQuery — kmeisthax/gridfinity-cadquery and michaelgale/cq-gridfinity
• OpenSCAD — vector76/gridfinity_openscad, ostat/gridfinity_extended_openscad, and kennetek/gridfinity-rebuilt-openscad

What stays constant across all of them

Gridfinity is a modular, open-source grid storage system, and the wiki sums up its core constraint: "The best things in life are integer multiples of 42x42x7mm." Every generator above produces parts on that grid, so the choice is about workflow and output format, not compatibility. The system is free, open source, and almost 100% 3D printable, first released by Zack Freedman under the MIT license and now maintained by a community that continually adapts it.
