Overture empty spool weight
Use these sourced tare weights to estimate how much filament remains on a Overture spool. Spool designs and production batches can change, so weighing your own empty spool is still the most precise method.
Standard spool (1 kg filament)
147 g empty spool
Manufacturer source · Nominal filament: 1000 g
Overture lists an empty spool weight of approximately 147 g across multiple current 1 kg filament lines. Treat it as an estimate, not an exact tare for every production batch.

How to calculate filament remaining
Weigh the loaded spool, then subtract the empty-spool tare weight. For example, a loaded spool weighing 720 g with a 220 g empty spool has about 500 g of filament remaining.
