- 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.
