Non-Drive Side Crank[edit]

Project developed by Zhinek (talk) 07:19, 04 December 2014 (PST)
Status
This OSAT has been designed but not yet tested - use at own risk.
This OSAT has been prototyped.

You can help Appropedia by contributing to the next step in this OSAT's status.

Abstract[edit]

  1. The project is a part of the bike, offered by Dr. John Gershenson.
  2. It is designed based on a real drive-side model since I only find drive-side model from the lab.
  3. I choose to design the non-drive side part since the strength of the gear can not be reached by using plastic material to print.
  4. All size are matched with the original one.

Bill of Materials[edit]

  1. 3D Printer
  2. Drive Side Crank Model
  3. Plastic filament

link to all source files[edit]

  1. File:Non-Drive Side Crank.scad
  2. File:Non-Drive Side Crank.stl

Tools needed for fabrication of the OSAT[edit]

Skills and Knowledge Necessary to Make the OSAT[edit]

  • Basic knowledge for 3D printing

Technical Specifications and Assembly Instructions[edit]

  1. Print from the base
  2. There is a curve that printed in the air, it's the most difficult part
  3. It can be printed but with low quality, needs to be corrected and polished
  4. Estimated printing time: 37min
  5. Estimated processing time: 15 min

Common Problems and Solutions[edit]

  1. It is made of plastic so it may not be as strong as metal.
  2. The edge of the crank is not perfectly smooth

Cost savings[edit]

  1. Estimated costs: less than $2 per crank (including the cost of the filament and electricity)
  2. Commercial equivalent: more than $10
  3. Save at least $8/80% of the cost

References[edit]

  1. Google picture for bike parts.
  2. Ebay website for pricing
