Abstract

  1. This OSAT Project helps multiple goals, primarily goal 10 by helping to make bike transportation more accessible and to decrease the cost and increase the ability to repair a bike that has a broken axle. This part was designed to replace the original axle on my 2017 Raleigh Tokul 3 mountain bike, but could easily be modified to fit any "Thru" style bike axle.
  1. This part features a hollowed center section to reduce the material used in the print, and otherwise uses a 75% infill for strength. The first iteration used a 50% infill, and due to that and a misplaced thread relief, it was not able to withstand the abuse of being ridden hard. The current model has been ridden and tested thoroughly, and has survived numerous hash riding conditions.
  1. To further increase the durability of this part a higher infill percentage could be used, and to increase the usability a Hex keyway in the threaded end of the shaft would allow for the axle to be properly torqued more easily.

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
    1. Upload and link to all source files from open source CAD
    2. Upload and link to all STLs

Tools needed for fabrication of the OSAT

  1. MOST Delta RepRap or similar RepRap 3-D printer

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, cite it and put the [url in square brackets]
  3. Calculate $ savings and % savings

Benefited Internet Communities

  • Name and add links to at least 5 using single brackets around [url name]
