- The colorFabb 2.2 kg spool measures 300 mm across the flanges, 100 mm wide, with a 52 mm hub hole, as published by OnlySpoolz (community spool database).
- 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.

## Questions

**What size is the colorFabb 2.2 kg spool?**

300 mm outer diameter, 100 mm wide, 52 mm hub hole (11.81 × 3.94 in, 2.05 in hole).

**Does the colorFabb 2.2 kg spool fit a Bambu Lab AMS?**

Bambu Lab lists the AMS HT for spools 197–202 mm in diameter and 50–68 mm wide; at 300 × 100 mm this spool is outside that range on paper, so plan on an adapter or an external holder.
