- threemf_stream reads Bambu Studio / OrcaSlicer project metadata: plates
(name, objects, preview images), filaments, and each part's type and
extruder. Placements now record which build item and part they belong to.
- convert_3mf.py leaves out negative/modifier/support parts, colours each
part by its filament (a part's extruder 0 falls back to its object's), and
takes --plate N. Geometry is still stored once per (part, colour).
- New threemf_info.py lists plates and filaments without loading geometry
and extracts plate preview images; served via /api/{files,entries}/:id/project.
- /glb?plate=N builds and caches a per-plate preview. Cached GLB names carry
a converter version, so previews made before colours are rebuilt.
- Model detail: plate chips (with the slicer's plate images) under the
viewer — multi-plate projects open on plate 1 — plus "All plates", and a
Filaments section with colour swatches.
- Fingerprints leave out negative/modifier parts, so a project matches the
model it prints.
