3D-print export functionality for `img2threejs` generated models.

Technical Positioning
Expanding the utility and target audience of `img2threejs` to the 3D printing and maker communities by providing direct export of watertight, print-ready models.
SaaS Insight & Market Implications
This issue identifies a significant market expansion opportunity for `img2threejs` by enabling 3D-print export. The current limitation is that generated `THREE.Group` models are not directly printable, excluding the maker and 3D-printing communities. Implementing watertight geometry baking, standard export formats (STL/OBJ/glTF), and basic print-prep features (manifold checks, wall-thickness warnings) will unlock this new segment. For B2B SaaS, this demonstrates a strategic move to diversify product applications and capture new revenue streams beyond digital-only use cases. The market demands versatile 3D asset generation tools that support multiple downstream workflows, including physical production. This feature directly enhances the product's value proposition for industries like rapid prototyping, custom manufacturing, and consumer goods.

Raw Developer Origin & Technical Request

Source Icon GitHub Issue Jul 17, 2026
Repo: hoainho/img2threejs
3D-print export: image to printable model (STL/OBJ/glTF + print prep)

## Motivation

img2threejs output is a procedural `THREE.Group` — great for the browser, but not directly printable. A single "image → printable 3D model" path would open the project to the maker / 3D-printing community.

## Scope

- Bake a generated `THREE.Group` into a single merged, **watertight** `BufferGeometry` and export **STL / OBJ / glTF**.
- Basic print-prep: manifold/normals check, a wall-thickness warning, and scale-to-mm with a target longest-edge.
- Note (honestly) where a single-image reconstruction leaves hidden faces mirrored/approximated — printability depends on it.

## Pointers

- `ROADMAP.md` (v1.4 — glTF export)
- `root.userData.sculptRuntime` exposes the node/collider hierarchy to walk during the bake.

## Acceptance criteria

- `export --format stl` (or equivalent) produces a sliceable STL for the loot-chest demo that loads clean in a slicer.
- A manifold check reports non-watertight geometry instead of silently exporting a broken mesh.
- Documented limits: which subjects print well vs. need manual repair.

**Difficulty:** medium–hard. A great fit for someone who prints — real-world test prints as PRs very welcome.
