Filament spool sizes

Hi, im making a custom filament spool for my printer, i print mainly polymaker pla, is there a difference between the spool size for the 1kg and 3kg filament spools? i assume the internal diameter is the same, just the width of the spool is different.
Also, are there any precautions to be taken with using a 3kg spool with a lulzbot mini due to the increased spool weight. Thanks!

Hey,
That’s correct the spool is the same size, just wider. With the LulzBot Mini, you won’t need to do anything to the printer to mount the larger spool, just load and go!
