## Tools (as reported by the server, not verified)

- `search`: Search everything on PrintPal for a 3D-printing query: community 3D models, free tools and calculators, wiki troubleshooting articles, OpenSCAD/AI-CAD docs, video tutorials, build guides and Academy courses. Returns ids accepted by \`fetch\` for the full content. Suited to general 3D printing question
- `fetch`: Fetch the full content of a PrintPal item returned by \`search\` \(or any id of the form \`model:\<uid\>\`, \`tool:\<slug\>\`, \`wiki:\<slug\>\`, \`doc:\<slug\>\`, \`resource:\<slug\>\`, \`project:\<slug\>\`, \`course:\<slug\>\`\). Returns the complete text \(article body, transcript, build steps, BOM, model description and files\)
- `search\_3d\_models`: Find printable 3D models \(STL/3MF/OBJ\) in the PrintPal community library by keyword — e.g. "articulated dragon", "headphone stand", "Raspberry Pi 5 case". Returns cards with thumbnail, author, tags, likes and a link to the model page where the files can be downloaded. Searches existing uploads only;
- `get\_3d\_model`: Get full details for one PrintPal model by uid: description, license, file formats, author, stats, and the page URL to download it. Accepts a uid from \`search\_3d\_models\` results or a printpal.io/model/\<uid\> URL.
- `find\_3d\_printing\_tool`: Recommend the right free PrintPal browser tool for a task: print cost / resin cost / layer height \(magic numbers\) / E-steps / flow rate / volumetric flow / filament spool / drying / shrinkage / Vref / Etsy profit calculators; generators for lithophanes, vases, name plates, 3D text, QR codes, bins, p
- `calculate\_print\_cost`: Estimate what an FDM print costs \(material, electricity, machine wear, labor, failure allowance\) and a suggested selling price. Needs the print weight in grams and time in hours from the slicer; all other inputs have sensible defaults \(1 kg spool at $20, 120 W printer, $0.12/kWh, 5% failures\).
- `calculate\_filament\_usage`: Convert filament grams to metres \(and back\), compute volume and cost, and estimate how much is left on a spool from its gross weight. Knows densities for PLA, PETG, ABS, ASA, TPU, Nylon, PC, CF blends. Give either \`grams\` or \`meters\`.
- `calculate\_layer\_heights`: Compute the Z-axis "magic number" layer heights for a printer from its stepper step angle, microstepping and lead-screw pitch/starts, filtered to what suits the nozzle. Defaults match most Ender/Prusa-style printers \(1.8°, 1/16, T8 2 mm × 4 starts → 0.04 mm steps\).
- `calculate\_volumetric\_flow`: Check whether a hotend can keep up: volumetric flow \(mm³/s\) = layer height × line width × speed, compared against the hotend limit, plus the maximum safe speed. Accepts a hotend preset name \(stock, v6, bambu, volcano, rapido, high-flow, goliath…\) or an explicit max flow.
- `search\_build\_guides`: Find step-by-step PrintPal build guides: Arduino/ESP32 electronics + 3D-printed enclosures, robots, functional prints, printer mods, STEM classroom projects, props and toys. Each result lists difficulty, time, cost, part/file/step counts. Filter by category \(electronics-robotics, functional-prints,
- `get\_build\_guide`: Read a full PrintPal build guide by slug: summary, bill of materials with quantities and links, downloadable files \(STL/3MF/code\), every build step, callouts and code blocks. Use when the user wants to actually follow or adapt a project.
- `search\_learning\_resources`: Search PrintPal's how-to content: the vendor-neutral 3D printing wiki \(print quality, filaments, slicer settings, maintenance, error codes, safety\), OpenSCAD + AI-CAD docs, short video tutorials with transcripts, and free Academy courses with certificates. Use \`type\` to narrow. Results include ids a
- `generate\_3d\_model`: Turn a text prompt or an image into a print-ready 3D mesh \(STL/GLB/OBJ geometry\) with PrintPal's AI generator. Without a PrintPal API key this returns a link that opens the generator on printpal.io with the prompt prefilled; nothing is generated until the user clicks it. With an API key header \(\`Aut
- `check\_3d\_generation`: Poll a PrintPal AI generation started with \`generate\_3d\_model\` in API-key mode. Returns status \(queued/processing/completed/failed\) and, when completed, a time-limited download URL for the mesh.
- `design\_parametric\_cad`: For mechanical / functional parts with exact dimensions — brackets, enclosures, adapters, gears, bins, knobs, mounts — open PrintPal's AI CAD agent with a ready-to-run brief. The agent writes editable OpenSCAD with parameter sliders, live 3D preview and STL/3MF/STEP export. This tool improves the us
- `get\_pricing\_and\_plans`: Explain what is free on PrintPal, how AI generation credits and the CAD agent are priced, API access and the on-demand 3D printing service — with links to sign up, buy credits or subscribe. Call when the user asks about cost, limits, subscriptions or how to get more generations.
