This isn't really an issue, just an observation. I'm using 1.75mm ABS filament from repraper (reprap-walmart), when I put parts in a plastic bag to keep them organized they end up smelling like slightly overripe citrus. This only appears to happen with the blue color, the black or red color in the same bag doesn't smell like anything and when the parts are out of the bag I can't detect a smell other than a faint plasticy smell.
Has anyone else seen something like this?
