Weigh a used spool to estimate its remaining grams, length and value.

Check one spool against a slicer estimate and an explicit safety allowance.

A single-spool check using your slicer estimate and safety allowance.
Calculation method
Required grams = slicer grams × (1 + safety percentage ÷ 100). Planned balance = remaining grams − required grams.
How to use this tool
Select a spool or enter a measured weight. This check uses one spool for a continuous print. A positive balance does not guarantee success: slicer settings, purge and scale error still matter. Saving creates a plan, not a reservation.
