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
- 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?
- Picture of completed print using
Bill of Materials
- Provide a full BOM -- Materials needed for fabrication of device and alternative materials if they are not available, prices/sources of non-printable parts
- Upload and link to all source files from open source CAD
- Upload and link to all STLs
- 2x M3x0.5 10mm screw cost=$0.13
- 2x M3x0.5 12mm screw cost=$0.15
- 2x M3x0.5 16mm screw cost=$0.16
- 1x M8x1 50mm bolt cost=$0.39
- 1x M8x1 nut cost=$0.09
Tools needed for fabrication of the OSAT
- [Athena Build Overview| MOST Delta RepRap] or similar RepRap 3-D printer
- 1x 2.5mm Allen Wrench
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
- 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

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.
- Total Cost = $2.32
- Hardware cost = $0.92
- Plastic Cost- 61 grams at $23/kg = $1.40
- Commercial equivalent Alm Retractor Cost=$191
- $188.68 savings
- 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]

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]].
