Improved PET Bottle Stripper
Project developed by Klbarie (talk) 20:25, 6 December 2015 (PST) Template:Statusboxtop Template:Status-prototype You can help Appropedia by contributing to the next step in this OSAT's status. Template:Boxbottom
Abstract
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.
Bill of Materials
- 1 - File:BottleStripper v2.stl
- 1 - File:Mounting Base v2.stl
- 1 - File:Razor Clamp v2.stl
- 2 - File:Spool Clamp v2.stl
- 1 - File:Spool Handle 1 v2.stl
- 1 - File:Spool Handle 2 v2.stl
- 1 - File:Spool Rod v2.stl
- 2 - File:Spool Stand v2.stl
- 2 - M3X10mm Bolts
- 8 - M3X16mm Bolts
- 10 - M3 Nuts
- 10-20 - M3 Washers
- Many - Standard Utility Blades
Tools needed for fabrication of the OSAT
- Athena Delta RepRap or equivalent 3D printer
- PLA or ABS plastic filament
- .STL Slicer program (Cura/Slic3r/etc.)
- Appropriate driver for chosen bolts
Skills and Knowledge Necessary to Make the OSAT
- Proficient knowledge in 3D printer operation
- Basic mechanical assembly skills
Technical Specifications and Assembly Instructions
- Download files listed above
- Print specified number of parts
- Clean parts as needed with a razor blade
- Assemble parts as shown in the Completed Assembly photo above.
* Use 10mm bolts to clamp razor blade * Use 16mm bolts to secure parts to base (add washers as needed if bolts stick too far past bottom of the base)
Common Problems and Solutions
- Cutting slots may need trimming before use
- Bottles tend to begin to cut into plastic stripper over time. May need to replace with metal substitute.
Cost savings
- ~252grams plastic filament - ~$7.32USD @ $29USD/kg
- No commercial equivalent can be found (other self made solutions, but no detailed drawings found)
- Savings is in time from self-spooling action
