Free Filament here's how!

With most of us dumping PET in the form of Plastic Bottles it's ridiculously easy to use them in your printer. If only I had enough time in my day but one or more of you might actually try this out. It's a brilliant concept, an innovative idea that would solve the problems of irregularities caused by using flaked or shredded PET through an Auger setup caused by uneven size, air gaps, and feed speed, this method converting flat or square input to round is theoretically simple. Step one: Unroll the bottle into PET string as effortlessly demonstrated by this genius guy. http://sploid.gizmodo.com/genius-guy-transforms-plastic-bottles-into-super-strong/ is where I found the instructions. Here's another great resource: http://wonderfulengineering.com/heres-how-you-can-make-a-strong-wire-or-rope-out-of-your-used-plastic-bottles/. A 3D printed version courtesy of a commenter, thank you for that! I'm sure most of this project already exists in one form or another. It just needs to be brought together. Step two: A print head that can be fed by flat string extruding filament in 1.75 or 3mm format is a great starting point. Overlapping short sections should be easy enough to produce continuous filament. You could also feed in short lengths of filament left on reels to prevent waste and create multi color filament using the same method. Step three: Link step one and two so that the motor feeding the extruder powers the stringer, stripping the bottles with a bit of preparation and loading but yielding free filament and maximum recycling at its best. Let me know if you try this out! I'll get around to it someday but for now, work is getting in the way. Calibration 2020.stl would be too large to publish without being downloadable.
