- **Search by meaning** — switch the search box to *Meaning* to find models by what they are ("wall hook" finds a "coat hanger bracket"). Uses a small embedding model (bge-small-en-v1.5, ~34 MB) that runs on the server, so it's free and private; the index updates in the background as models change.
- **Automatic tags** — strict whole-word rules over names, file names and archive contents (part types, mechanisms, materials, techniques) plus your own "word → tag" rules. Switch it off (optionally removing its tags) or re-apply it any time. Tags you add yourself are never changed; AI and rule tags are marked on the model page.
- **Filament & what's printable** — keep the spools you own (material, colour, brand, grams left) on the **Filament** page. Bambu Studio / OrcaSlicer projects name the filament in each slot, which Printhive reads once per model in the background, so cards and the model page say whether you can print it now and what you're short of, and the toolbar can show only what's printable. Each slot is matched to a spool by material *and* colour — a four-colour print needs those four colours, and one spool can't fill two slots. Near shades count as the same colour; the model page lists every slot, which spool fills it, and the nearest thing you own when none does. Models that aren't slicer projects don't name their filaments, and say so rather than being called unprintable. The slot list can be edited on the model page when the project's own list is wrong or you plan to print it differently — set a slot to **any colour** when the shade doesn't matter, and it's filled by any spool of that material. Edited lists are marked as yours and left alone by the background reader; "Use the project's list" puts it back. Adding a spool can start from Bambu Lab's own filament list — pick "PLA Basic — Jade White (10100)" and the material, colour and code fill themselves — and slot colours are named where they match it. That list is included by kind permission of [3D Filament Profiles](https://3dfilamentprofiles.com), whose terms otherwise reserve it; ask them before reusing `db/bambu-filaments.json` elsewhere.
- **Printer** — connect a Bambu Lab printer on your network in Settings → Printer (its address, serial number and access code), and "Save & test connection" listens to it for a few seconds and reports what it said: its state and the filament in each AMS slot or on the external spool holder. The connection is read-only — Printhive never sends the printer a command — and the access code stays on your server.
- **Trash** — deleting moves a model to the trash; restore it, delete it forever, or empty the trash (only then are files removed from disk).
- **Settings** — API tokens / FlareSolverr URL stored in the database (with `.env` fallback), secrets masked.
