Generate custom gridfinity bins with AI, from photos of your tools

What it solves

Tracefinity automates the creation of custom 3D-printable storage bins for the Gridfinity modular system. Instead of manually measuring tools and designing CAD models, users can generate precise tool-shaped cutouts simply by taking a photo of their tools on a piece of standard paper.

How it works

Users place tools on a standard sheet of paper (A4, Letter, etc.) and take a top-down photo. The software uses AI to calibrate the scale based on the paper's corners and then traces the tool outlines. These outlines are converted into editable polygons that can be refined in a tool editor. Users then arrange these tools into a bin layout, and the system generates STL or 3MF files for 3D printing, including features like finger holes, chamfers for easy insertion, and multi-color contrast inserts.

Who it’s for

It is designed for 3D printing enthusiasts and makers who use the Gridfinity storage system and want to create perfectly fitting, custom-organized tool drawers or workspaces.

Highlights

  • AI-Powered Tracing: Supports local models (IS-Net, BiRefNet Lite, InSPyReNet) for privacy and cost, or the Gemini API for higher accuracy.
  • Automatic Scaling: Uses standard paper sizes to calibrate real-world dimensions from photos.
  • Advanced Bin Customization: Includes options for cutout clearance, chamfered edges, recessed/embossed text labels, and bed splitting for large prints.
  • Tool Library: Allows users to save traced tool silhouettes to reuse them across different projects.
  • Live 3D Preview: Integrated three.js preview to visualize the bin before exporting for print.

    Graphify-Labs/graphify

    Graphify is a Python CLI that builds a local, LLM‑free knowledge graph of a codebase (and optional docs/media) using Tree‑sitter. The graph can be visualised, queried, and integrated with many AI coding assistants (Claude, Copilot, Cursor, Gemini, etc.) to answer questions, trace connections, or explain symbols without grepping files.

    visualbruno/ComfyUI-Trellis2

    ComfyUI‑Trellis2 is a custom‑node pack that integrates Microsoft’s TRELLIS.2 3‑D diffusion model into the visual programming UI ComfyUI. It provides dozens of nodes for generating, refining, texturing, and rendering meshes from single or multi‑view images (or video). Installation requires Windows, Python 3.11, PyTorch 2.7/2.8 with CUDA, and the Facebook DINOv3 checkpoint. The repo ships pre‑built wheels for native extensions and includes example workflows. It’s an active, genuine AI/ML project aimed at 3‑D generation.

    pixel-point/toolcraft

    Toolcraft is an open‑source starter kit and UI library for building custom, browser‑based design tools (image filters, gradient generators, animation editors, etc.). It ships a React + TypeScript + Tailwind stack, a pan/zoom canvas, a rich component library, layer/timeline support, export utilities, and a set of prompts that let AI coding assistants (Codex, Claude, Cursor) scaffold and extend the app via a simple CLI (`npx @pixel-point/toolcraft create`). The generated project runs locally (default http://localhost:3002) and can be deployed anywhere. MIT‑licensed, cross‑platform, and intended for developers who want AI‑assisted rapid prototyping of niche design workflows.

    lynote-ai/ai-image-detector

    AI Image Detector is an open‑source Python tool that estimates how likely an image was generated by AI. It ships with several ready‑made back‑ends (UnivFD, Sentry, Nonescape, hybrid ensembles) and lets you run a single command (`aidetect detect …`) on a file or folder, outputting a probability and label. Optional extras give a Gradio web UI or a FastAPI server. The repo includes benchmarking scripts, threshold‑calibration, and clear guidance on which backend to pick. It’s a lightweight, install‑once‑run‑anywhere utility for AI‑image detection, with documented limitations (no universal guarantee, no region‑level localization).
