The free Gridfinity toolset
Design and print anything Gridfinity.
Three tools in one place: design parametric Containers with dividers and labels, generate Baseplates, or Scan a photo to get a bin with a cutout shaped exactly to your tool. Free, browser-based, print-ready STL and multicolor 3MF.
Three tools, one suite
Everything Gridfinity, in your browser
All tools are free to use and export. A one-time payment unlocks a personal cloud library to save and organise your designs.
- Flagship
Scan
Photograph your tool on a calibration sheet. The AI isolates its outline and generates a Gridfinity bin with a cutout shaped exactly to it.
Open tool - Parametric
Containers
Design Gridfinity bins with compartments, dividers, magnet holes, stacking lip, label tabs, eco/lite walls, and multicolor layers.
Open tool - Parametric
Baseplates
Generate normal, skeleton, or weighted baseplates with magnet sockets, screw holes, adjustable border width, and snap connectors.

How Scan works
Four steps from photo to bin
This is the Scan flow. Containers and Baseplates are direct parametric editors: open them and adjust sliders, no photo needed.
-
Print the calibration sheet
Print the free sheet and place your tool on it. The printed markers tell Gridfinity Tools the real size and angle.
-
Take one photo
Photograph your tool on the sheet from above. Phone or webcam, both work.
-
Tap your tool
Tap once on the tool. The built in AI isolates its exact outline for you.
-
Download and print
Gridfinity Tools builds a Gridfinity compatible bin with a matching cutout. Export STL or 3MF and print.

Runs in your browser

FAQ
Common questions
-
Are all three tools really free?
Yes. Scan, Containers, and Baseplates are all free, including every option and every download (STL and 3MF). A one-time payment unlocks a personal cloud library with folders and subfolders to save and organise your designs.
-
Do I need an account to use the tools?
No account is needed to design and download. Sign up only if you want the cloud library to save your work across devices.
-
What do I need to print the calibration sheet?
The calibration sheet is only needed for Scan. Any A4, A3, or US Letter printer works. Containers and Baseplates are fully parametric and need no sheet.
-
Which printers are supported?
Any FDM or resin printer. Export STL or 3MF from any tool and slice as usual.
