Prema Lovrinom linku[1], 1kg ABS-a je 13m plastike. Koliko smo ono računali
da nas dođe nabavka 1kg ABS-a?

I don't think anyone's gone to the trouble of measuring one, but we
can estimate it with math. I quick google search tells me that ABS has
a density of 1.04 grams per cubic centimeter, so a 1kg spool should be
about 962cc. The nominal cross-sectional areas of 1.75mm and 3mm round
filaments are .02405 and .07069 square centimeters, respectively.
Divide the volume by those areas and you get a length of 39976
centimeters for 1.75mm and 13603 centimeters for 3mm.
