Spool Tracker - SpoolVault

Know exactly how much filament you have — and what every print costs. Add your whole shelf in minutes, then stop guessing for good.

SpoolVault is a filament inventory built for 3D printing. Weigh a spool, log a print, and you always know what's left, what it cost, and which printer or shelf it's sitting on.

ADD YOUR WHOLE SHELF IN MINUTES

Pick a brand and a material, tap every color you own, set how many of each, and save them all in one go. Then do the same for your next brand. Brands, materials and colors come preloaded for Bambu Lab, eSUN, Polymaker, Prusament, Hatchbox, Overture, Inland, Sunlu, Elegoo and BIQU.

KNOW WHAT'S LEFT ON EVERY SPOOL

Put a spool on any kitchen scale and enter the number. SpoolVault subtracts the empty spool's weight and tells you the filament remaining. Brand-specific spool weights are already built in, so it's a real figure, not a guess.

KNOW WHAT EVERY PRINT COSTS

Enter what you paid for a spool and SpoolVault works out the material cost of every print from the grams used — so you finally know what the thing you just made actually cost.

KNOW WHERE EVERY SPOOL IS

Assign spools to a printer, an AMS or multi-material slot, and a storage location — drybox, shelf, cupboard, wherever they really live. Then find any color in seconds.

GROUP A BUILD INTO A PROJECT

Multi-plate print? Group the plates under one named project and see total filament used, estimated material cost, and a full breakdown of every spool that went into it.
