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:

• Print Projects Group multiple plate prints under a named project and see the total filament used, estimated material cost, date range, and filament breakdown in one place. Combine existing prints into projects, unlink plates when needed, pin important projects, and delete projects with or without their linked prints.

• Preloaded filament catalogue Includes preloaded brands, materials, and colours for Bambu Lab, eSun, Polymaker, Hatchbox, Overture, Inland, Prusament, Sunlu, and more — or add your own custom brands and colours.

• Accurate spool weight system Use preloaded, brand-specific spool weights to calculate how much filament remains on each spool.

• Print cost tracking Add filament purchase prices and SpoolVault can estimate the material cost of each print based on the grams used.

• Fast inventory setup Add filament quickly using preloaded catalogue data, or customise your setup with your own brands, colours, spool weights, printers, and storage locations.

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.
