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.
Capabilities
AI Agent Discovery
PrintNexus Toolbox is indexed by Tedix as a structured ai application listing for AI assistants, search crawlers, and users comparing agent-ready apps.
- PrintNexus Toolbox has no primary catalog category yet; Tedix treats this as a routing gap for browse and recommendation surfaces.

Auth, tools, and actions
Authentication: Open Access. PrintNexus Toolbox is flagged for Can Modify Data. Current MCP inventory reports 3 tools, 1 resources, and 0 prompts.
- Download lithophane · App action
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.
- Load image · Read-only action
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.
- Lithophane Maker · Read-only action
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.

Server Instructions
PrintNexus Toolbox provides 3D printing tools. Use a tool only for what its description says. Lithophane Maker supports flat, single-color models. Answer capability questions and requests for unsupported shapes or color separation without opening the maker. Do not create or open a flat, single-color alternative as a fallback, demonstration, or just in case. An attached image, width, or requested STL/3MF does not authorize substituting a flat model for an unsupported request. You may offer a flat alternative in text, but wait until the user explicitly requests or accepts it before calling make_lithophane. Open the maker for a supported creation request or an explicit request to choose an image. Converting an existing image into a printable lithophane model is different from generating a new picture. For conversion, use the user-selected image file reference, including a generated image when ChatGPT makes its reference available. Ask which image if the choice is ambiguous; never invent references or silently substitute another image. When a tool opens a panel, wait for the context the panel shares before describing results. A prepared file is not proof that a download completed.
