Best Photo-Based Gridfinity Generators in 2026

Photo-based Gridfinity generators let you snap a picture of your tools on a sheet of paper and get a print-ready tray with precision cutouts — no CAD skills needed. The category has grown quickly, and there are now four serious options plus one open-source project.

We built GridPilot, so we have skin in the game. This comparison is still honest: we give credit where it's due, call out where competitors do things better, and keep every claim verifiable. If anything here goes out of date, let us know.

The Tools

All four tools follow the same basic workflow: photograph your tools on a sheet of white paper, upload the photo, and the software traces the tool outlines and generates a Gridfinity-compatible tray. The differences are in what happens after the trace — specifically, how much of the final tray the tool actually builds for you.

Feature Comparison

The Key Split: 2D Outlines vs Full 3D Models

The most important difference between these tools is what they actually generate. Some produce 2D tool outlines that get extruded into a flat plate with cutout holes. Others generate a complete 3D model with proper walls, a solid floor, Gridfinity-standard stacking feet, and a stacking lip.

If you are printing Gridfinity trays, this distinction matters. Stacking feet are what lock the tray into a Gridfinity baseplate so it does not slide around when you open your drawer. A stacking lip lets trays stack securely on top of each other. Without these, you just have a tray sitting loosely in a grid — which defeats the purpose of the Gridfinity system.

GridPilot and gridfinity.tools generate full 3D models with stacking feet. TracetoForge and Tooltrace generate 2D outlines that require additional CAD work to add Gridfinity features. This is not a value judgment — if you are laser-cutting foam, a 2D outline is exactly what you want. But if you are 3D printing Gridfinity bins, a full 3D model saves you from opening Fusion 360 or FreeCAD to add the features yourself.

GridPilot

GridPilot uses AI-powered computer vision to detect tool outlines from photos. The pipeline generates a complete 3D Gridfinity tray with proper pocket walls, controlled per-tool pocket depths, stacking feet, an optional stacking lip, and embossed text labels on each pocket.

Unique features include auto-layout (the app arranges multiple tools into the most space-efficient configuration automatically), auto-size (the tray grid dimensions are calculated from the tools you place), and embossed labels printed directly into the bin geometry so they survive painting and wear. Export formats include STL, 3MF (with separate label objects for multi-color printing), SVG, and DXF.

The free tier includes 100 square inches of tray area per month — enough for 2–3 standard Gridfinity trays. Paid plans start at $3.99/month with unlimited exports. Mobile upload works on both iOS and Android — take the photo on your phone, then finish the design on desktop or continue on mobile.

Best for: anyone who wants a complete, print-ready Gridfinity tray from a photo without opening CAD software. Especially strong if you want labels, stacking lip, or need to arrange multiple tools in one tray automatically.

TracetoForge

TracetoForge runs OpenCV edge detection entirely in the browser. No server-side processing — your photos never leave your device. The tool traces tool outlines and produces Gridfinity-compatible bins with cutout pockets, exporting as STL, 3MF, SVG, and DXF.

The privacy angle is a legitimate strength: if you work in an environment where uploading photos is restricted, TracetoForge's fully client-side approach is a real advantage. Multi-tool layouts support up to five tools per bin. SVG and DXF output makes it useful for laser-cutting foam or wood inserts, not just 3D printing.

TracetoForge does not generate stacking feet, a stacking lip, or embossed labels in the tray geometry. The output is a bin with cutout shapes. Adding Gridfinity stacking features requires post-processing in CAD software.

Pricing is credit-based: tracing and 3D preview are free, exports cost credits ($9.99 for 20 credits, $34.99 for 100). New accounts get three free export credits. Credits do not expire.

Tooltrace

Tooltrace's standout feature is dual-mode output: the same trace can produce either a Gridfinity bin or a Kaizen foam shadow box pattern. If your workshop uses both 3D-printed inserts and foam-cut organizers, Tooltrace bridges both from a single photo.

Tooltrace includes built-in magnet hole support, which is useful for Gridfinity bins that need to lock onto magnetized baseplates. Multi-tool layout support is more limited than GridPilot or TracetoForge as of the last review.

Free tier includes three trays. Paid plan is $8/month. Export formats are STL only — no 3MF, SVG, or DXF.

gridfinity.tools

gridfinity.tools is the only tool in this list that combines parametric and photo-based generation. If most of your bins are simple rectangular dividers (where you type in dimensions) with occasional tool-shaped cutouts (where you need a photo), having both in one app avoids switching between tools.

The photo-based mode generates full 3D models with stacking feet, similar to GridPilot. The parametric mode handles baseplates, divider bins, and standard storage compartments. gridfinity.tools is fully free for both modes.

The trade-off is scope: gridfinity.tools does not have embossed labels, auto-layout, or stacking lip generation. If those features matter, you will need a different tool for photo-based bins.

Open-Source Alternative: tracefinity

tracefinity is an open-source GitHub project for the same photo-to-Gridfinity workflow. If you are comfortable cloning a repo and running it locally, it is free with no limits and fully modifiable. For everyone else, one of the hosted tools above will be faster to get started with.

Pricing for a Real Project

Say you want to print 10 custom Gridfinity trays for a workshop refit. Here is what each tool costs, ignoring filament ($1–3 per bin in PETG regardless of generator):

FAQ

Which produces the best trace accuracy?

All four tools use some form of computer-vision edge detection. In practice, trace accuracy depends more on your photo quality than the tool. Flat lighting, white paper background, and a top-down phone angle produce clean results in any of them. If you are getting poor traces, improve the photo before switching tools.

Which works on my phone?

GridPilot, TracetoForge, and gridfinity.tools all work in mobile browsers. GridPilot supports direct camera capture from your phone — take the photo and upload without leaving the app. Most users find it easiest to take the photo on their phone and do the layout and export on desktop, but the full workflow runs on mobile if needed.

Do I need to take a new photo, or can I use an old one?

Any standard JPEG or PNG works. The photo does not need to be taken specifically for the tool — as long as the tools are on a known-size reference (usually a sheet of paper), reasonably lit, and shot from above, the workflow works.

Can I mix photo-traced and manual shapes in one tray?

GridPilot supports this: you can add rectangular or circular manual cutouts alongside photo-traced tools in the same tray. Useful for things like batteries, pens, or other items where a photo trace is overkill and a simple rectangle works better.

Which is easiest for a complete beginner?

Any of them will get you a usable bin on the first try with a decent photo. Pick by feature match and pricing, not by perceived ease of use — the core workflow (upload photo, adjust, export) is similar across all four.

Bottom Line

The photo-based Gridfinity generator category is healthy — there is no single "best" tool for every use case. The right choice depends on what you are actually printing and what workflow you want.

All four have free tiers or free trials. The best way to decide is to run the same set of tools through two or three of them and compare the output.
