Spoolwise: Filament Tracker

Spoolwise keeps track of your 3D printer filament: what's on every spool, what each print cost, and when a spool needs drying. Free, with no spool limit, no subscription, no account, and it works offline. YOUR SHELF - Every spool with its colour, material, brand, location and how much is left - Search by colour, brand, label code or location; filter by material or "running low" - Sort by most recently used, colour, material or what's left - Add a multipack in one go: four identical spools, four label codes HOW MUCH IS LEFT, REALLY - Put the spool on a kitchen scale: Spoolwise takes off the empty spool and corrects what's left - Empty-spool weights for plastic, cardboard and refill spools, or weigh your own - Remaining shown in grams, percent and metres (from the material's density and diameter) - Run-out forecast from how fast you've been using it PRINT LOG AND COST - Log a print with the grams or metres your slicer shows; it comes off the spool - Multi-colour or split prints across several spools - Cost per print from what you paid per spool, plus electricity per printer if you like - Edit or delete a print and the filament goes back on the spool - Success or failed, print time, notes, "print it again" DRYING - Drying temperature and time for PLA, PETG, ABS, ASA, TPU, nylon, PC, PVA and more - Log drying runs; see days since the last one and when moisture-hungry materials need another - Warns before drying a cardboard spool too hot LABELS AND LISTS - Printable QR labels on Avery 5160 (Letter) or L7160 (A4) sticker sheets - A short code on every spool (S-0042) to find it again in seconds - A printable inventory list of the whole shelf STATS - Filament used per month, by material and by colour - Spent on prints, cost per print, success rate, value of what's on the shelf YOUR DATA STAYS YOURS - Everything is stored on your phone: no account, no cloud, no login to break - Back up everything to one file and restore it on a new phone - Export spools and prints to CSV; import spools from a spreadsheet or another app Works with any printer and any brand: PLA, PLA+, PETG, ABS, ASA, TPU, PA, PC, PVA, HIPS, carbon-fibre blends and your own materials. Densities and drying times are typical values from filament makers; your spool's label always wins. 3D printing filament tracker, filament inventory, spool manager, print cost calculator, filament drying log: Spoolwise, free and ad-supported, from Fernhart Labs.
