3MF — Manufacturing Cube
A 10 mm cube as 3MF — the modern OPC-packaged manufacturing format (a ZIP of model XML plus relationships). For testing 3MF readers and slicers.

What is a .3mf file?
3MF (3D Manufacturing Format) is a modern XML-based 3D printing format packaged as a ZIP archive, designed to fix STL's limitations by including color, materials, units, and multiple objects. It carries full model and print metadata in a single file. It is increasingly the preferred format for 3D-print workflows.
How to use this file
Use an example 3MF to test ZIP-package and XML parsing, color and material handling, and modern slicer or print pipelines that preserve rich model metadata.
How to use this file for testing
“3MF — Manufacturing Cube” is a deterministic Novus Examples fixture for Conversion testing. The same content exported across many formats and linked as a group, so you can convert one and diff against the expected twin.
Documented properties for this file: 3MF (OPC package). Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
3D and CAD fixtures carry one small, documented solid or scene. Convert and inspect against the known geometry, units, and structure; format twins let you diff interchange fidelity, and the 3D viewer previews the actual mesh.
