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.
Possible additions to bike pedal:
- Add screw attachment at the end of the axle
- Develop more secure clips (these were tough to model and print)
Bill of Materials[edit | edit source]
- Plastic Filament (PLA preferred)
- All files (FreeCAD and .stl) can be found on Youmagine at: https://www.youmagine.com/designs/bike-pedal-38-29
Tools needed[edit | edit source]
- 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[edit | edit source]
- Be sure you are able to load an STL into a slicer and orient it the correct way
- Basic understanding of bike pedals
Technical Specifications and Assembly Instructions[edit | edit source]
- Fabrication Instructions
Common Problems and Solutions[edit | edit source]
- Don't forget to put support everywhere on the pedal halves. Be sure to select "Everywhere" instead of "Touching Buildplate".
- Ensure all pieces are printed with the orientation shown.
Cost savings[edit | edit source]
- The cost to print the full pedal is approximately $2.50
- Walmart sells two pedals for $7.99 
- Savings are $3.00 per two pedals which is savings of 37.5%
