Been building this for a couple of weeks now but I can now say I have made a 3D Benchy from a PET 1 drinks bottle. The machine is called the ReCreator and it basically pulls 8mm wide strips of plastic bottles through a modified hot end to form it into filament. I got around 6.5m of usable filament from one bottle for reference.
Info on the machine here or find it on Printables
A few picture of my machine, will upgrade/reprint parts as and when required.
