TWO SPOOLS · ONE IMPORTANT DIFFERENCE
200 g total.
Only two 60 g jobs.
Leftovers on separate spools cannot finish a third job without a filament change.

Bring your full sliced-job estimate. See what fits without a mid-job change.
Cover the real gap.
Compare your own quotes. Enough material already? Buy nothing.
