I purchased the filament from a well known supplier here in Australia (BilbyCNC). There is no place of manufacture on the reel. Unless there are manufacturers of inexpensive filament in the Americas or Europe I guess that this filament comes from China. Bear in mind that the differences in dimensions were of the order of 0.05mm. An extruder nozzle hole could be that much out of round.

The point that I was making was that it is important to know the diameter of your filament if you are involved in commercial production, and that you should not use the nominal diameter in your slicer software configuration. I would suggest that the figure of 2.94 be used for calculations.
