 "repo_slug": "shpigford-nurb",
 "title": "Catch print problems before the printer runs",
 "page_title": "How to catch print problems before the printer runs with Nurb",
 "summary": "Run Nurb's printability rules on a part to find overhangs, thin walls, and floating islands early.",
 "who": "A maker or developer who wants to avoid failed prints and checks each part before sending it to the printer.",
 "problem": "Failed prints waste filament and time, and many problems such as thin walls are hard to spot by eye in a model.",
 "outcome": "A list of findings with coordinates that point to the exact faces where each rule fired.",
 "steps": [
  "Install Nurb with `uv tool install nurb` or `pip install nurb`.",
  "Run `nurb check` to run the printability rules on the project's parts.",
  "Run `nurb inspect` to see faces, normals, concave edges, and each finding on its face.",
  "Fix the design in the part file or card, then run `nurb check` again.",
  "Add `nurb check --strict` to your CI so findings fail the build. (inferred, check the README)"
 ],
 "agent_prompt": "Using the nurb repo (Shpigford/nurb), run the printability checks on the part <target part name> in this project. Expected output: a list of findings such as overhang or min_wall with coordinates. Verify by running `nurb inspect` and confirming each finding appears on a face.",
 "agents": [
  "any"
 ],
 "difficulty": "Intermediate",
 "time": "45 minutes",
 "basis": "readme",
 "caveat": "The README warns that min_wall samples faces, so a clean result means no thin walls were found, not that none exist.",

 "lang": "python",
 "requirements": [
  "An AI subscription you already pay for, such as one that works with your agent or terminal",
  "A Mac (the app is provided for Apple silicon and Intel) or a terminal with uv or pip available",
  "A 3D printer and a slicer such as OrcaSlicer or Bambu Studio, if you want print time and filament estimates"
