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.

Tools needed
Skills and knowledge needed
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
