Abstract
- The project is a part of the bike, offered by Dr. John Gershenson.
- It is designed based on a real drive-side model since I only find drive-side model from the lab.
- 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.
- All size are matched with the original one.
-
Non-Drive Side Crank
Bill of Materials
- 3D Printer
- Drive Side Crank Model
- Plastic filament
link to all source files
Tools needed for fabrication of the OSAT
- MOST Delta RepRap or similar RepRap 3-D printer
Skills and Knowledge Necessary to Make the OSAT
- Basic knowledge for 3D printing
Technical Specifications and Assembly Instructions
- Print from the base
- There is a curve that printed in the air, it's the most difficult part
- It can be printed but with low quality, needs to be corrected and polished
- Estimated printing time: 37min
- Estimated processing time: 15 min
Common Problems and Solutions
- It is made of plastic so it may not be as strong as metal.
- The edge of the crank is not perfectly smooth
Cost savings
- Estimated costs: less than $2 per crank (including the cost of the filament and electricity)
- Commercial equivalent: more than $10
- Save at least $8/80% of the cost
References
- Google picture for bike parts.
- Ebay website for pricing
