- Spot low-stock spools before you start a 12-hour print
- Find the right spool instantly — filter by material, brand, or color
- Material breakdown shows your PLA-to-PETG ratio at a glance

- Brand, material, color & weight auto-populated

Smart Alerts
Don't start a 12-hour print
only to run out at hour 8.
Failed prints from empty spools. Brittle parts from wet filament. Ordering the wrong material because you forgot what you had. Spooldex catches these problems before they waste your time and money.
Never run out mid-print
Set low-stock thresholds per spool. Spooldex warns you before you start a print you can't finish.
Stop printing with wet filament
PETG, Nylon, and TPU absorb moisture and print terribly. Get drying reminders before quality suffers.
Know before you press Start
Check if you have enough of the right material before committing to a print. No more surprises.
