Sample PSD, DXF, STL and OBJ files — free download
Design, CAD and 3D fixtures generated from source — a flattened PSD, a PDF-compatible AI, an EPS, an R12 DXF drawing, and the same cube as OBJ, STL, PLY and glTF.
8 ready-made design, CAD and 3D test files
| File | Size | What it catches | |
|---|---|---|---|
| cube.obj | 221 bytes | The most common interchange mesh format. Plain text; catches loaders that assume 1-indexed vs 0-indexed faces (OBJ is 1-indexed) and those that cannot triangulate. Watertight closed mesh. | download |
| cube.ply | 343 bytes | Point-cloud and scan tooling. ASCII header declaring element counts then data; catches parsers that ignore the declared vertex/face counts. | download |
| vector.eps | 391 bytes | The PostScript branch of design-file handling - distinct from the PDF-based .ai. Catches importers that only special-case PDF and treat EPS as opaque, and print pipelines that must rasterise PostScript. | download |
| cube.stl | 684 bytes | The 3D-printing standard. Binary (80-byte header + triangle count + 50 bytes/triangle); catches parsers that only handle ASCII STL, and slicers that need consistent normals. | download |
| drawing.dxf | 743 bytes | CAD import and DXF parsing. DXF is plain group-code/value text, so it catches importers that assume a binary CAD blob, and the R12-vs-R2000 structural split (this is the widely-compatible R12 form, with heavyweight POLYLINE rather than the newer LWPOLYLINE). Generated from source. | download |
| illustrator.ai | 863 bytes | Handlers that assume .ai is EPS/PostScript and choke on the PDF-based form, and MIME sniffing that must tell an .ai apart from a plain .pdf. Opens in Illustrator, Preview and any PDF viewer. | download |
| cube.gltf | 1.3 KB | The modern web/AR 3D standard. JSON referencing binary accessors; catches viewers that only accept .glb (binary glTF) or external .bin buffers and choke on an embedded data URI. | download |
| photoshop.psd | 48.0 KB | Whether your pipeline recognises a real PSD (magic bytes "8BPS") rather than trusting the extension, and whether a preview/thumbnail step can flatten one. Generated from source - no stock imagery. | download |
Every file is generated from source — no third-party copyright — and each has its own page with a published SHA-256 you can verify after download.
Questions
Where can I download a sample PSD file?
The PSD below is a minimal flattened 8-bit RGB document — small, valid, and free of any licensed artwork.
Do you have sample STL or OBJ files for 3D printing tests?
Yes — the same unit cube in OBJ, STL, PLY and glTF, so you can compare importers against identical geometry.
Which DXF version is the drawing?
R12 (AC1009), the most widely supported DXF version, using heavyweight POLYLINE entities rather than R2000-only LWPOLYLINE.
