PET Bottom Cutter

Overview:I wanted to speed up the process of preparing PET bottles for making filament. One of the steps is to cut the bottom of the bottle. Using scissors is not very convenient and fast so I have designed this cutter which uses a snap-off blade. The blade is rotated by hand using a simple crank mechanism.The PET_Bottom_Cutter_Insert.stl is added for smaller bottles (1.5l) with diameter ~88mm. For these bottles it is beter to use the short version of the blade holder - PET_Bottom_Cutter_Blade_H
