Project developed by Hannah Stoll
- This hand powered machine is a food processing tool that will grind peanuts down so they can be made into peanut butter. There aren't many 3D printable milling devices out there. This entire mill is 3D printed and was designed with all open source technology. Food processing mills and machines are expensive to buy, so this printable one allows people in need to have tools that work.
Bill of Materials
- Fully 3D printable (I used 1.75mm PLA filament)
- Upload and link to all source files from open source CAD
- Upload and link to all STLs
Tools needed for fabrication of the OSAT
- MOST Delta RepRap or similar RepRap 3-D printer
Skills and Knowledge Necessary to Make the OSAT
Technical Specifications and Assembly Instructions
- Provide directions for print/assembly - be detailed enough in your “how to” to ensure that someone could construct the device from your description. Consider the elegance of IKEA like instructions.
- Include print time estimate
- Include assembly time estimate
- Including drawings or pictures of the device at stage of assembly at minimum. (http://www.appropedia.org/Special:Upload)
- Consider video if appropriate
|Example video summary of textbook|
Common Problems and Solutions
- Include common mistakes/problems to avoid in building your OSAT and how to overcome them
- If your solution is not a low cost one then it is not really appropriate.
- Estimate your costs
- Find a commercial equivalent
- Calculate $ savings and % savings
Benefited Internet Communities
- Name and add links to at least 5 using single brackets around [url name]
- The sources of information (e.g. engineering handbooks, journal articles, government documents, webpages, books, magazine articles etc.). References should use the <ref> </ref> and <references/> tags and can be in any format but should include all the information necessary for someone else to find the same information you did. For example: 
- web page: Department of Energy (DOE) Landscaping and Energy Efficiency, DOE/GO-10095 (1995) Available: http://www.eren.doe.gov/erec/factsheets/landscape.html
Based on the developmental needs addressed (e.g. food, heat, electricity, clean water, health care, etc.) be sure to label your device in the proper categories e.g. use [[Category:Water]]. Be sure to categorize your device so that it will be easy to find – for example “Low voltage connection basics” is categorized in [[Category:How tos]] [[Category:Electricity]] [[Category:Electric lighting]].
