Remaining-filament spool gauge

Estimate how much filament is left on a spool

Rest the shoulder on the rim of a 1 kg spool's 200 mm flange and see which step the filament surface reaches: the steps mark 75, 50, 25 and 10 % left, worked out from the wound volume rather than the depth, so you know whether the spool will last a long print before you start it.
