Spool Tracker – Smart Measurement Tool for 3D Printing Filament
The Spool Tracker V1 is a precise, Wi-Fi-enabled measurement tool designed to automate filament tracking. With just one NFC scan, it identifies the spool, measures its weight using a digital load cell, and sends the data directly to Google Sheets.
Built with an ESP8266 and intuitive LED feedback, this compact device eliminates manual logging and guesswork. Whether you're a maker or managing a print farm, the Spool Tracker delivers reliable, automated measurement and inventory control — all in one tap.
