In many countries, disposing of PET bottles has caused a major problem. Recycling these bottles proves a difficult challenge. This Bottle Stripper turns PET bottles into long strips that can be used to weave baskets, use as fishing line, use as a type of rope, or possibly even as 3D printer filament. This design spools the strips automatically as it operates.

In many countries, disposing of PET bottles has caused a major problem. Recycling these bottles proves a difficult challenge. This Bottle Stripper turns PET bottles into long strips that can be used to weave baskets, use as fishing line, use as a type of rope, or possibly even as 3D printer filament. This design spools the strips automatically as it operates.
