Filament inventory

One row per physical spool on your shelf. Deduct grams after each print and see what is left in grams, meters and money — no spreadsheet, no Docker. Presets come from your filament library. Everything is stored locally in this browser.

Meters assume 1.75 mm filament and typical material density; the tare weight is kept for scale weigh-ins (gross − tare = filament left). Spools under 20% remaining are flagged in the danger color. Value is priced at what you paid per gram. To cost a specific print, use the quote calculator.
