From this premium 1.5L water bottle I get approx 25g or 10m of final filament, this is because these bottles have very little waste and a wall thickness of 0.35mm which allows me to cut them to 7mm width, do not expect to get more than 5 meters of filament from an ordinary 1.5L water bottle. Also these water bottles are not consumed by me, a neighbor brings me a few each week. I buy 8L bottles for drinking and cooking which give me 27m or 66g each.

The speed is between 16 to 20 cm per minute.
