Tim's PET Bottles to Filament (Part 1 - Bottle Cutter)

This video is about the Filament maker I am in the process of making. It is the Bottle Cutter, I have done an Instructable here: https://www.instructables.com/Tims-PE... I am afraid this project has been put on the back shelf for the moment. I am sure you have seen people pulling these strips of plastic through a hot end of a 3D printer. I fell for it. The filament that is produced is hollow, it is a tube. There is about 60% missing inside the filament and you will have to adjust the 3D printer to compensate for this. I did some calculations (I should have done this at the start) and decided it was not feasible, you should be getting about 5 meters of 1.75mm filament from a bottle, the rest (any longer) equates to air with this process. I had a go at pushing it through but I was not able to push it fast enough and control the temperature close enough, I don't have the resources to do what was needed. I have some other ideas, but it will have to wait until I can get the resources I need.
