Sample OBJ File — Download a Wavefront 3D Model Test File
Wavefront OBJ 3D model · .obj · MIME type model/obj
Download a sample OBJ file — the same pine-tree mesh as our STL sample in Wavefront OBJ, with v vertex records and f face records and no material file. OBJ is the text-based interchange format that Blender, Maya, Unity, three.js and most CAD tools import.
Because it is plain text with a simple grammar, OBJ is a good first fixture for anyone writing a 3D importer, and a good acceptance test for 3D-asset upload pipelines.

Frequently asked questions
Why does the model have no colours or textures?
OBJ stores materials in a separate .mtl file and textures as image files; this sample omits both to stay self-contained. Most viewers render it in a default grey, which is expected.
Are these OBJ files safe to download?
Yes. Every file is generated by our own open script from scratch — nothing is scraped or user-uploaded — and contains no scripts, macros or executables. The SHA-256 of each file is published on this page so you can verify what you received.
Can I use the sample OBJ files commercially?
Yes. They are free for any purpose, including commercial products, test suites, demos and redistribution, with no attribution required. There is nothing to license and no one to ask.
Can I hotlink these files or use them in CI?
Yes. Every link is a stable direct URL over HTTPS with Access-Control-Allow-Origin: * and long cache headers, so curl, wget, fetch() and test runners can pull them directly. A JSON index of every file is linked from each page (see the command-line section).

Uploads, conversions, previews, document processing and media workflows are the kind of production systems Pine & Birch designs and runs for clients — which is why we needed these files in the first place.
