If 1kg filament does not fit on the same spools you use for the 1/2kg spool, USE A LARGE SCREEN. This is the worst spool of filament I have ever bought. This cannot print without the edge of the spool falling off and becoming tangled unless I stand next to the printer and load it manually. I expect more from a "Made in the USA" product.
