WIP : PET bottle strip cutter for recycle them to 3Dprinter filament

This design is made to cut PET bottle to recycle them into 3Dprinter filament.

created for the recreator from Josh ( https://www.facebook.com/groups/recreator3d/ )

The cartridge is made to easily change the strip height (from 1 mm to 13mm)

Just add a coin in the cartridge to slowdown the friction of the PET to the printed part.
