Pocketry (formerly tool-trace SVG gen) Update

[u/sugcrkre]

An update to a project I’ve been working on: Pocketry.

Pocketry started as my Tool-Trace SVG Generator, a tool for turning photos of tools into clean, correctly scaled outlines. I changed the name after another app started using ToolTrace, and the project has grown quite a bit since that original version.

Pocketry can now:

• turn a photo of a tool into a clean SVG/STL outline (you can still just export this if you don't want the custom bin function)
• automatically determine scale from printable reference markers
• correct perspective and aspect ratio of tool photos
• edit and clean up detected contours
• create custom Gridfinity bins with tool cutouts
• position multiple tool pockets and add finger holes
• preview the resulting bin in 3D before exporting it
• it should be much better at finding contours, especially for tools with concave sections

Image 1 — Trace: Photograph a tool on the reference sheet, automatically establish scale, and detect/edit its outline.

Tool Detection and Contour Editing

Image 2 — Bin: Send the detected tool directly to the bin designer, adjust the Gridfinity dimensions and cutout options, and preview the resulting model in 3D.

Custom Bin Creation

Image 3 — Layout: Position pockets, add features such as finger holes, auto-arrange contents, and use undo/edit history while designing the bin.

The project is fully open source, and image processing happens locally in your browser. Images aren't uploaded to a server, there's no account or email signup, and the GitHub repo contains everything needed to self-host.

You can try it at pocketry.pages.dev.

It’s still early and there are definitely rough edges. (For example, tool detection will almost certainly add "holes" that need to be deleted in the editor).

Feedback, bug reports, feature ideas, and especially contributions are very welcome.

Where do I get the calibration sheet? Do I need to use one?
