Spool Tracker - SpoolVault

Know exactly how much filament you have — and what each print costs.

SpoolVault is a filament tracker built for 3D printing, helping you track filament usage, monitor remaining spool weight, calculate print costs, and manage your filament inventory with precision.

No more guessing. No more wondering what’s left. No more losing track of how much filament your prints actually use.
SpoolVault is designed to make filament tracking fast, accurate, and practical:

- Accurate spool weight tracking
Know exactly how much filament is left on every spool, using preloaded, brand-specific spool weights for precise remaining-weight calculations.

- Print cost tracking
Add your filament prices and SpoolVault estimates the material cost of every print from the grams used — so you finally know what each print really costs.

- Fast inventory setup
Load your collection in minutes from a preloaded catalogue of brands, materials, and colours — Bambu Lab, eSun, Polymaker, Hatchbox, Overture, Inland, Prusament, Sunlu, and more — or add your own. Then organise by printer, AMS / multi-material slot, and storage location, with custom spool weights to match your setup.

- Print Projects
Group multiple plate prints under a named project to see total filament used, estimated material cost, and a full filament breakdown in one place.


Core Features:
• Track remaining filament weight per spool
• Log filament usage after every print
• Calculate filament cost per print
• See what’s left before starting your next print
• Manage active spools and sealed spools
• Organise filament by printer, AMS / multi-material slots, and storage location
• Customise brands, colours, and spool weights to match your setup
• Search, sort, and filter your filament collection

Built for serious makers who want precision, not guesswork.

Know your filament. Track your costs. Print with confidence.
