Alm Retractor

Project developed by Robert Arden

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
    Wood WorkingClamp Parts.png

Bill of Materials

  1. Provide a full BOM -- Materials needed for fabrication of device and alternative materials if they are not available, prices/sources of non-printable parts
  2. Upload and link to all source files from open source CAD
  3. Upload and link to all STLs
  4. 2x M3x0.5 10mm screw cost=$0.13
  5. 2x M3x0.5 12mm screw cost=$0.15
  6. 2x M3x0.5 16mm screw cost=$0.16
  7. 1x M8x1 50mm bolt cost=$0.39
  8. 1x M8x1 nut cost=$0.09

Tools needed for fabrication of the OSAT

  1. MOST Delta RepRap or similar RepRap 3-D printer
  2. 1x 2.5mm Allen Wrench

Skills and Knowledge Necessary to Make the OSAT

  • Only standard 3D printing skills needed for this project

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

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. Total Cost = $2.32
    1. Hardware cost = $0.92
    2. Plastic Cost- 61 grams at $23/kg = $1.40
  2. Commercial equivalent Alm Retractor Cost=$191
  3. $188.68 savings
  4. 98.8% 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 [[Category:How tos]] [[Category:Electricity]] [[Category:Electric lighting]].
