What's a spool?

The reel your filament comes wound on, usually a kilogram of plastic.

Meet SpoolOne tangle can ruin a twelve-hour print. No wonder Spool is nervous.

Why it matters

  • A tangle or a snag stops the filament, and the print fails.
  • Most filaments soak up moisture from the air, and wet filament prints badly.

Tips from the workshop

  • Clip the loose end into the spool’s edge holes when you put it away.
  • Store open spools in a sealed box with desiccant.
  • Weigh the spool before a long print, so it doesn’t run out halfway.
