Most 3D-printing hobbyists track their filament in a messy spreadsheet — or not at all. Then a 12-hour print stops at hour 10 because the spool ran dry, or you buy a third roll of black PLA you didn't need. A dedicated filament inventory tracker keeps your whole stash visible so you always know what you have and what it's worth.
Open PrintLog →Add each spool with its brand, material, color, total weight, weight remaining, cost, opened date, and whether it's been dried. PrintLog shows a live fill bar per spool, so you can see at a glance which rolls are nearly empty before you start a big print.
Set a low-stock threshold and PrintLog flags any spool that drops below it, so you can reorder before you're stuck. The dashboard totals your spool count, the kilograms of filament on hand, and your overall inventory value — handy when filament is a real chunk of your hobby budget.
When you log a print, you can link it to a spool and have the grams used subtracted automatically — so your remaining weights stay accurate without manual maths. With Pro ($9 one-time) you also get filament usage & cost stats and CSV export of your full inventory.
