# meshy-3d-printing

Turns Meshy models into files a slicer can take: scale, orientation, analysis, repair and multicolor output. Useful when a design has to leave the screen.

## What it does

The skill covers the path from a model to print-ready output. Local steps need no account: `mesh prepare-print` resizes and grounds an existing OBJ, while `slicer detect` and `slicer open` find and launch an installed slicer. Cloud stages — geometry generation, texturing, auto-split — run through Meshy CLI 0.4.3.

Picking a route is straightforward. A single-colour model comes from text or a photo with no textures. Multicolor printing means texturing after analysis and repair. Repair alters geometry and wipes textures, so materials have to be reassigned downstream. Creative Lab items follow their own sequence: prototype, review, build, then choose the product files.

Some limits are worth knowing up front. A local input cannot exceed 50 MiB, and the model must be GLB or glTF (GLB for multicolor). STL, OBJ and FBX are accepted only as http(s) links. Cloud jobs get submitted once with `create --async` and waited on as the same task. Local preparation and printability analysis cost nothing; the skill asks before any extra paid step.

A slicer opens only when the request or an existing authorization covers it. Without checking supports and wall thickness, the file is not guaranteed to print.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add meshy-dev/meshy-3d-agent --skill meshy-3d-printing -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/meshy-3d-printing/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/meshy-3d-printing/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add meshy-dev/meshy-3d-agent --skill meshy-3d-printing -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/meshy-3d-printing/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add meshy-dev/meshy-3d-agent --skill meshy-3d-printing -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/meshy-3d-printing/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install meshy-dev/meshy-3d-agent meshy-3d-printing
```

2. **Manually: put the files in place**
- File: `.github/skills/meshy-3d-printing/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add meshy-dev/meshy-3d-agent --skill meshy-3d-printing -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/meshy-dev/meshy-3d-agent --path skills/meshy-3d-printing
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/meshy-3d-printing/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add meshy-dev/meshy-3d-agent --skill meshy-3d-printing -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/meshy-dev/meshy-3d-agent/tree/HEAD/skills/meshy-3d-printing/SKILL.md

## When to use it
- scale an OBJ to a target height and ground it
- check a model for printability against a printer type
- split a model into parts for separate printing
- prepare a multicolor print with textures
- hand a finished file to the installed slicer

## Example prompts
- Prepare `figure.obj` for printing at 120 mm tall and send it to the slicer
- Generate a white model from this photo and check whether it prints
- Make a multicolor version of this figurine and build a 3MF for printing

# Meshy 3D Printing

Use Meshy CLI **0.4.3** to deliver the requested print files at the intended size, with
analysis/repair results where applicable and a slicer handoff when requested. This skill is
self-contained. Ordinary digital assets belong to meshy-3d-generation.

| Need | Reference |
|---|---|
| CLI runner, credentials, or output location | [Setup](references/setup.md) |
| Local preparation, cloud generation, or product workflow | [Printing recipes](references/printing.md) |
| Cost, waiting, preview, delivery, or finding a previous model | [Delivery](references/delivery.md) |
| Failed or uncertain operation | [Troubleshooting](references/troubleshooting.md) |

Read relevant sections as needed. Recipes illustrate valid commands; select only the stages
needed for the user's output.

## Choose local or cloud work

| Request | Route |
|---|---|
| Scale, orient or ground an existing OBJ | Local `mesh prepare-print`; no auth or balance |
| Open an existing STL or 3MF | Local `slicer detect` and `slicer open`; no auth or balance |
| White model from text or photo | Generate geometry without textures; analyze/repair as needed; prepare the file |
| Multicolor model | Generate/reuse geometry; analyze/repair as needed; texture; multi-color-print |
| Print in separate parts (build plate, colours per part, fewer supports) | Generate/reuse geometry; auto-split; slice the parts |
| Creative Lab figure, vinyl figure, brick figure, lamp, keychain, fridge magnet, keycap or pixel fidget board | Prototype → review → build → select product artifacts |
| Creative Lab collapsible fidget | One create from the photo → STL |

A figurine does not by itself require Creative Lab. Infer the route from the intended product;
ask about size, color or style only when the missing choice materially changes the result.
For an existing model, distinguish local preparation from cloud printability analysis; a
local dimension check cannot establish full printability.

## Cloud authorization

Resolve the runner automatically using Setup (compatible `meshy` or
`npm exec --yes --package=meshy-cli@0.4.3 -- meshy …`). Local-only work stops at runner setup.
Cloud work reuses a verified session. If login is needed, keep `auth login --device` running,
