## Overall (mm)

| length | width | height |
|---|---|---|

**Exact dimensions.** True size, with no printing tolerance added.

## Notes

- The SUNLU PLA 1 kg spool measures 195 mm across the flanges, 60 mm wide, with a 75 mm hub hole, as published by OnlySpoolz (community spool database).
- SUNLU has changed spool designs over time; this entry is the plastic spool recorded by the database, with an unusually large 75 mm hole.
- 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.
