{{777}} == Non-Drive Side Crank == Project developed by [[User:Zhinek|Zhinek]] ([[User talk:Zhinek|talk]]) 07:19, 04 December 2014 (PST) {{Status|design}} {{Status|prototype}} == 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. <gallery> Image:Non-Drive Side Crank.JPG|Non-Drive Side Crank </gallery> == Bill of Materials == #3D Printer #Drive Side Crank Model #Plastic filament == link to all source files == #[[File:Non-Drive Side Crank.scad]] #[[File:Non-Drive Side Crank.stl]] == Tools needed for fabrication of the OSAT== * [[Delta_Build_Overview:MOST| 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 [[Category:Outdoors]] [[Category:Sports]] [[category:OSAT 3D-Printable Designs]]
