I have tried a ton of differnt spools and for the speed, the fialment used and the look of the spool this one from https://makerworld.com/en/models/16747#profileId-15531 Brandido02 is one of hte best. The only thing I did was a the section for Babmbu label to be affixed to on the spool to note the material.
Enjoy the spools as much as I have
