PET Bottle Shredder
Project developed by [1] Template:Statusboxtop Template:Status-design Template:Status-prototype You can help Appropedia by contributing to the next step in this OSAT's status. Template:Boxbottom
Abstract
Included below is three different designs for PET bottle shredders currently designed for 20oz soda bottles but easily expandable for use with 2 liter soda bottles. The first design is a simple hand held shredder which is the simplest design and uses the least plastic. This makes this design ideal for areas which have access to a 3D printer but which filament might not be as readily available. The second design adds a bottle holder to the simple hand held shredder. This holder was added to possibly aid in efficiency. The third design is a hand cranked design which also uses a bottle holder and spools the cut filament. These shredders allow the use of the cut PET to be used in things like crafts and possibly for printing purposes.
Bill of Materials
- 3-D printer
