Read a 3MF package
==================

3MF is the modern interchange format for additive manufacturing. It
carries per-object geometry, names, colors, and units in a single
archive. This example loads a real 3MF from the 3MF Consortium sample
set (BSD-2-Clause): a colored dodecahedron chain from the material
extension.

Why this matters: slicers like PrusaSlicer and Cura key off the
per-object content inside the 3MF. Reading it straight into a
:class:`pyvista.MultiBlock` keeps a design flow headed for print.
