Notes

  • The Prusament 1 kg spool measures 200 mm across the flanges, 68 mm wide, with a 51 mm hub hole, as published by OnlySpoolz (community spool database).
  • Prusa Research does not publish a spool drawing; these are a community database's measurements of a Prusament PETG spool.
  • The file is a solid envelope cylinder at the outer diameter and width with the hub hole through it; flange thickness, core diameter, ribs and windows are not modelled.
  • No manufacturer drawing was found, so these are a secondary source's published measurements; check a real spool before printing a tight-fitting part.
  • True size, no printing tolerance added. Only published numbers are used; anything not published is said so.
  • Secondary source: the numbers come from a retailer or magazine copy of the maker's specification.
