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.

Bill of Materials

Plastic Filament (PLA preferred)
1. Upload and link to all source files from open source CAD
2. 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

Example video summary of textbook
Error in widget YouTube: Unable to load template 'wiki:YouTube'

Common Problems and Solutions

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

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.

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]].

-|Image:1_Pedal.JPG| Print bottle cap at .2mm layer height or less, with the threads at the top, without supports. Support material clogs up the threads, creating unnecessary cleanup work. Estimated print time at 70mm/s: 22 minutes.
+|Image:1_Pedal.JPG| 1. After downloading all .stl files from Youmagine, begin by printing two halves of the pedal with the orientation shown. Ensure there is enough support. Print time: 3 hrs 18 mins each half at 70 mm/s
-|Image:2_Pedal.JPG| Print the tea bag holder as shown at .3mm layer height. Estimated print time at 70mm/s: 42 minutes.
+|Image:2_Pedal.JPG| 2. Print six clips with the orientation shown. Print time: 1 min each at 70 mm/s
-|Image:3_Pedal.JPG| Cut open a teabag at an edge and add one teaspoon activated carbon.
+|Image:3_Pedal.JPG| 3. Print one axle with the orientation shown (for smoothest surfaces). Print time: 38 mins at 70 mm/s
-|Image:4_Pedal1.JPG| Stuff tea bag with carbon into the large end of the bag holder.
+|Image:4_Pedal1.JPG| 4. Place all six clips and the axle on one half of the pedal as shown.
-|Image:5_Pedal.jpg| Screw cap onto bottle threads.
+|Image:5_Pedal.jpg| 5. Place second half of pedal on top as shown.
-|Image:6_Pedal.jpg| Fully seat the cap into the tea bag holder.
+|Image:6_Pedal.jpg| 6. Apply force to snap clips into place. The final product is as shown. Assembly should take a total of no more than 2 minutes.

-# 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
