Here’s the 3D printing spools I have weighed so far. If I remember down the track I shall update with the sizes of the >1kg spools, as they can vary quite a bit!
Knowing the spool weights is very helpful for quickly figuring out how many grams are left on a roll.
eSun 5KG spool: 786gm
eSun 3KG spool: 633gm
eSun 1kg spool: 260gm
Polymaker 3KG plastic spool: 412gm for a PLA one, 430gm for an ASA spool so far.
3DFillies 3KG spool: 702gm
Standard Print Co. 3KG plastic spool: 458gm
