Notes

The Filamentive 300-500 g spool measures 200 mm across the flanges, 40 mm wide, with a 50 mm hub hole, as published by Filamentive.
Filamentive uses the same 200 mm flange for its small spools but only 40 mm of width, which is narrower than the AMS minimum.
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.
True size, no printing tolerance added. Only published numbers are used; anything not published is said so.

Questions

What size is the Filamentive 300-500 g spool?

200 mm outer diameter, 40 mm wide, 50 mm hub hole (7.87 × 1.57 in, 1.97 in hole).

Does the Filamentive 300-500 g 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 200 × 40 mm this spool is outside that range on paper, so plan on an adapter or an external holder.
