Bike Pedals
Project developed by [Mitchell DeNooyer]

Abstract
- A bike is a very useful mode of transportation that many people in first-world countries take for granted. There has been a goal set to create a cheap bike using primarily 3D printed parts. This bike pedal is a good prototype for what the possibilities are for this project. This pedal is fully 3D printed and clips together around a bar/axle. The goal is that this pedal would be easy to switch out and allows for rotation around the axle but not in other directions. This is still a rough prototype and would need more work to be implemented fully onto the bike.
- Picture of completed print using your printer
Bill of Materials
- Plastic Filament (PLA preferred)
- Upload and link to all source files from open source CAD
- Upload and link to all STLs
Tools needed for fabrication of the OSAT
- MOST Delta RepRap or similar RepRap 3-D printer
- Knife of some sort to clean up parts
Skills and Knowledge Necessary to Make the OSAT
- Be sure you are able to load an STL into a slicer and orient it the correct way
Technical Specifications and Assembly Instructions
- Download all .STL files from above or within the Youmagine link
- Load Pedal_Half_Final.STL into a slicer
- Orient pedal half so that the clip holes are on the top. Add support everywhere to ensure quality
- Print two pedal halves(These will clip together later)
- Load Axle_Final.STL into a slicer
- Orient it so that it requires no support
- Print one axle
- Load Clip_Final.STL into a slicer
- Orient the clip so that the greatest amount of surface area is touching the build plate
- Print six clips
- Place all six clips in one half of the pedal
- Place Axle within the trough
- Connect other half of the pedal with the other half of the clips
- 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.
- Include print time estimate
- Include assembly time estimate
- Including drawings or pictures of the device at stage of assembly at minimum. (http://www.appropedia.org/Special:Upload)
- Consider video if appropriate

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.
- Estimate your costs
- Find a commercial equivalent, cite it and put the [url in square brackets]
- Calculate $ savings and % savings
Benefited Internet Communities
- Name and add links to at least 5 using single brackets around [url name]
References
- The sources of information (e.g. engineering handbooks, journal articles, government documents, webpages, books, magazine articles etc.). References should use the <ref> </ref> and <references/> tags and can be in any format but should include all the information necessary for someone else to find the same information you did. For example: [1]
- ↑ web page: Department of Energy (DOE) Landscaping and Energy Efficiency, DOE/GO-10095 (1995) Available: http://www.eren.doe.gov/erec/factsheets/landscape.html
Based on the developmental needs addressed (e.g. food, heat, electricity, clean water, health care, etc.) be sure to label your device in the proper categories e.g. use [[Category:Water]]. Be sure to categorize your device so that it will be easy to find – for example “Low voltage connection basics” is categorized in [[Category:How tos]] [[Category:Electricity]] [[Category:Electric lighting]].
