Filament Shelf

Find owned filament, remaining weight, and storage location in seconds.

Filament Shelf is a local-first inventory for 3D-printing filament.

Keep filament products and physical spools organized separately, then search by material, color, label, manufacturer, tag, or storage location. See the known remaining weight across matching spools and open a product to check each spool's location.

Your inventory works offline and does not require an account. Export an app-owned JSON backup when you choose, and import it again after reviewing a clear replacement warning.

Key features:
- Fast shelf search across filament details and storage locations
- Separate product and physical-spool records
- User-managed remaining-weight estimates
- Custom locations for dry boxes, racks, and cabinets
- Duplicate suggestions while adding filament
- Local JSON backup and restore
- Eight supported interface languages

Remaining weights are estimates you maintain. Filament Shelf does not provide material-safety, drying, or print-success guarantees.
