Lightweight Wrenches

Project developed by Jackie Mayrose

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

  1. Paragraph description of the OSAT - why is it Appropriate? What need does it fulfil? Are there case studies you have found of a technology being used successfully?
  2. Picture of completed print using

Bill of Materials

1. Your choice of filament

    • Based on printer capabilities, cost, availability.
    • Parts shown printed in PLA. ABS is probably best.

2. [broken Thingiverse OpenSCAD files]

    • Editable OpenSCAD file for making different size wrenches
    • Common sizes of wrench also in STL

Tools needed for fabrication of the OSAT

  1. MOST Delta RepRap or similar RepRap 3-D printer
  2. Utility/hobby knife or similar (small saw)
  3. Pliers optional but helpful

Skills and Knowledge Necessary to Make the OSAT

  • If you used special skill – link to relevant wikipedia or wikiversity articles/courses

Technical Specifications and Assembly Instructions

  1. 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.
  2. Include print time estimate
  3. Include assembly time estimate
  4. Including drawings or pictures of the device at stage of assembly at minimum. (http://www.appropedia.org/Special:Upload)
  5. Consider video if appropriate
Example video summary of textbook
Error in widget YouTube: Unable to load template 'wiki:YouTube'

Common Problems and Solutions

  • Include common mistakes/problems to avoid in building your OSAT and how to overcome them

Cost savings

  • If your solution is not a low cost one then it is not really appropriate.
  1. Estimate your costs
  2. Find a commercial equivalent
  3. Calculate $ savings and % savings

References

  • 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: [1]
  1. 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
