Integration details

Description

PrintNexus Toolbox brings 3D printing tools into ChatGPT for makers and 3D printing enthusiasts. With Lithophane Maker, turn an image into a flat lithophane: a thin 3D printed plate that reveals the image when light shines through it. Set the width in millimeters, inspect the model in an interactive 3D preview, and compare lit and backlit views. Download your model as an STL or 3MF file. The current release supports flat lithophanes printed in one color. More 3D printing tools are planned for future updates.

Tools

3 tools agents can invoke

Used only by the Lithophane Maker panel: builds the 3MF or STL from the panel's gray grid and settings and returns a download link that works for 10 minutes.
export_lithophane
Use this when the user requests creation of a supported flat, single-color lithophane from an image, or explicitly asks to open the maker to choose an image. Do not use for capability questions or requests for cylindrical, curved, wraparound, multicolor, color-separated or AMS-ready models. Explain the flat, single-color limitation in text. Do not call this tool to create a flat alternative as a fallback, demonstration, or just in case, even when the unsupported request includes an attached image, width, or STL/3MF export. Offer a flat alternative in text and wait for the user to explicitly request or accept it before calling this tool. Example: a request to turn an attached image into a cylindrical lithophane and export an STL requires a text explanation only, with no maker call or replacement picture. A lithophane is a thin 3D-printed plate that reveals the image when backlit. The maker offers an interactive 3D preview, width and lighting controls, and STL or 3MF downloads. It converts an existing image, including an image generated earlier in the conversation; it does not generate another picture. Pass the selected image using the ChatGPT-provided file reference. When several images are present, use the one the user identifies; ask which one if ambiguous. Never invent a reference. For a supported creation request when ChatGPT cannot provide the selected image, open without image and guide the user to From library (when available) or Choose image in the panel. widthMm sets the overall plate width when requested.
make_lithophane
Used only by the Lithophane Maker panel: downloads the image passed to make_lithophane when the panel cannot fetch it itself. Returns the image to the panel only.
