Overall (mm): length 300, width 300, height 160
- The Polymaker 5 kg spool measures 300 mm across the flanges, 160 mm wide, with a 32 mm hub hole, as published by Polymaker.
- The 5 kg spool has a much smaller 32 mm hole than Polymaker's 55 mm cardboard spools, so standard spool-holder hubs will not fit it.
- 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.
