**FilamentVault** Your filament collection deserves more than a spreadsheet. FilamentVault is a complete workshop companion for 3D printing enthusiasts, designed to help you organize your filament inventory, understand how it is being used, and keep important spool information close at hand. **KNOW WHAT'S IN YOUR VAULT** Build a detailed inventory of your filament collection and track the information that matters, including brand, material, color, remaining weight, spool type, storage location, print settings, and more. FilamentVault gives every spool its own identity so your growing collection stays organized. **TRACK FILAMENT USAGE** Log print jobs and record the amount of filament used. FilamentVault automatically incorporates that usage into your spool's remaining weight so you can better understand what you have available for your next project. Need to correct a spool's weight?

Each spool maintains its own history, giving you a convenient record of how your filament has been maintained. **ORGANIZE YOUR WORKSHOP** Create custom storage locations and assign your spools to the places where you actually keep them. When a spool moves, FilamentVault can record the change so your inventory reflects your workshop. **IDENTIFY SPOOLS WITH QR & NFC** FilamentVault supports QR codes and NFC tags to help turn physical filament spools into part of your digital inventory.
