Polymend

ChatGPT plugin

Make 3D models printable

View in ChatGPT directory

Reviews a 3D model, repairs the small mesh faults that make a slicer complain (stray triangles, pinholes, reversed faces, split seams), stands it on the bed at the height you ask for, and writes an STL and a 3MF. Shows the model from four sides with every change marked, compares it with the reference pictures, and says what came out well and what did not. Works on GLB and STL files or links, up to 20 at once. Runs on your own computer in the ChatGPT desktop app and Codex (Node.js 20 or later); Polymend uploads nothing.

Example prompts

  • “Make this GLB ready to 3D print.”
  • “Repair these models for printing and give me STL and 3MF files.”
  • “Turn the 3D model you just made into a print-ready STL.”

Skills

  • images-to-print

    Turn pictures of a character or object into a physical 3D print. Use when the user wants a printable model made from reference images with a 3D generation tool they have connected (such as an image-to-3D plugin, or its command line) and then print files: it covers choosing the references, the cost question, checking the generated model, and handing it to the print-ready skill for repair, sizing, STL and 3MF, and a review.

  • print-ready

    Prepare GLB or STL 3D models for physical 3D printing with Polymend. Use when the user wants a 3D model (a local .glb or .stl file, or an https link to one, such as a model a 3D generation tool just made) repaired, sized and exported for a 3D printer or slicer: it fixes the mesh faults slicers warn about, sets the print height if one is given, writes an STL and a 3MF, draws the model from four sides with every change marked, and reviews what came out well and what did not. Not for printing documents or photos, and not for other 3D formats (OBJ, FBX, STEP).
