the internal spool diameter on this filament is 74mm which means you can't use it on almost any free standing holder, this is literally just a tube that fits inside the spool that makes it 66mm - that's it!

Default printer set ups I'm using it on Creator 3 - allows it to fit inside the enclosure without dragging on the bottom

Creator 2 pro/max - fits the default spool holders

FLSun top loaders: no longer drags on housing

Ender 3 v2 top loaders: no longer drags on frame

Creator 4: allows it to fit inside the enclosure without dragging on the bottom

Things I couldn't fix with this awful spool: Couldn't magically shrink it so it fits inside those heated box things (it's still too big for them)
