SpoolSync

SpoolSync is a practical companion app for 3D printing workflows built around OpenSpool NFC tags and Moonraker-compatible printers.

Create a local library of filament profiles, write filament data to NFC tags, read tags back, and use scanned tag data to update configurable filament slots on your printer over your local network.

Key features:
- Create and manage local filament profiles
- Store brand, material type, subtype, color, HEX value, temperatures, diameter, and spool weight
- Write OpenSpool JSON filament data to writable NFC tags
- Read OpenSpool NFC tags and save scanned filaments to your library
- Discover Moonraker devices on the same local network
- View printer details and currently loaded filament slots
- Select editable filament slots and update them from a scanned NFC tag
- Confirm updates by checking printer status after the change

SpoolSync is designed for local, hands-on 3D printing setups where you want a simple way to keep filament information consistent between physical spools, NFC tags, and printer configuration.

Requirements:
An NFC-capable device is required for tag reading and writing. Printer update features require a Moonraker-compatible printer reachable on the same local network. Availability of filament slot updates may depend on printer firmware and configuration.
