SpoolTags vs ReSpool

Never lose track of your 3D printer filament again. SpoolTags helps you organize, track, and manage all your filament spools with QR codes and NFC tags. SMART ORGANIZATION • Automatically group spools by manufacturer, material, variant, and color • Track starting weight, current weight, and empty spool weight • Get low-stock alerts when filament is running low • Archive finished spools to keep your library clean EASY IDENTIFICATION • Generate printable QR code label sheets (A4 format) • Scan QR codes to instantly find or create spool records • Support for NFC tags as backup identifiers (iOS) • Human-readable slugs like "brisk-wolf-0427" for quick reference SYNC EVERYWHERE • iCloud sync keeps your spool library updated across all devices • Works on iPhone, iPad, and Mac • Export to CSV for spreadsheet analysis PRINT-READY LABELS • Generate professional label sheets with QR codes • Multiple labels per spool (for spool sides, AMS cards, and spares) • A4 template optimized for standard label paper FREE TO START • Track up to 10 active spools for free • Archived spools don't count toward your limit • One-time purchase to unlock unlimited spools Perfect for makers, hobbyists, and anyone with a growing filament collection. Stop guessing what's on your spools and start tracking with SpoolTags.

ReSpool writes the NFC tag that Anycubic ACE 3D printers read to identify filament. Anycubic only sells spools with these tags, so filament from any other brand is invisible to the printer. ReSpool writes a blank NFC sticker with the material, colour and printing temperatures of whatever spool you actually have, and the printer then recognises it like its own. WORKS WITH HOME ASSISTANT Every tag gets a unique spool ID, carried in the SKU. The hass-anycubic_cloud integration reads it from the Anycubic cloud, so Home Assistant can tell two identical reels apart and track how much filament is left on each. Connect the app to Home Assistant and the Library shows what is left on every reel, straight from what the printer has extruded. THE WHOLE ANYCUBIC RANGE A catalogue of more than 600 genuine Anycubic product codes ships with the app and works offline — every colour of every line, with temperatures taken from scans of real spools. Pick a product and write it straight to a tag, or scan a genuine spool to add it for everyone. OPENPRINTTAG TOO Read and write Prusa's open standard, as shipped on every Prusament spool, on ICODE SLIX2 tags. OpenTag3D and OpenSpool are supported as well. HONEST ABOUT WHAT IS LEFT Put a part-used reel on the scales and the app works out the filament left, writes that to the tag, and can update it later on the same tag — same spool ID, same history. Photograph a spool to pick up its colour. TWO TAGS PER REEL The ACE reads one face of the reel. Write a second sticker for the other side carrying the same spool ID, so the reel is recognised either way up and Home Assistant still sees one spool. SAFE BY DESIGN - Only the data pages are ever written; the UID, lock bits and configuration pages are unreachable - A full backup is taken before a single byte is written, and can be restored - Every page is read back and compared byte for byte - A tag already holding spool data stops and asks first - Pages that already hold the right bytes are skipped Needs blank NTAG213 stickers (or larger); Anycubic's own tags are password-locked and cannot be reused. OpenPrintTag needs an ICODE SLIX2. Requires an iPhone 7 or later.
