Abstract

Accessing clean water is still a struggle for many people throughout the world. In areas devastated by natural disasters, it can take years for the infrastructure to be rebuilt. Makeshift water piping has been a massive undertaking in Nepal especially where an earthquake devastated the area a year ago. Organizations such as Field Ready are hard at work making sure water supply systems in the area are sanitary and helpful for those who need it. The T-fitting module was specifically requested by Field Ready to join hoses in the field to allow for more pipes to be ran while the entire system staying sanitary. The request Source can be found here.

Bill of Materials

• PLA Filament was used for printing all components. Components should be printable in other materials as well.
• All CAD models (STLs and SCAD) can be found on Youmagine.

1. One T Fitting (Printed Component)
   1. Cost: $1.12 for 56g of PLA Filament at $20/kg
2. Three Hose Caps (Printed Component)
   1. Cost: $0.34 for 17g of PLA FIlament at $20/kg each
3. O-Ring and Washer
   1. Already equipped with manufacturing O-rings for hoses as indicated here.
   2. Equivalent Market Cost $1.48 for 6 of each
4. Link to STLs and SCAD Files

Tools needed for fabrication of the OSAT

1. MOST Delta RepRap or similar RepRap 3-D printer
2. Sharp knife to remove excess filament from threads

Skills and Knowledge Necessary to Make the OSAT

• Knowledge of operating a 3D printer is required for manufacturing components.

Technical Specifications and Assembly Instructions

Assembly Instructions

1. 3-D print five slider segments with support material enabled.
2. Including drawings or pictures of the device at stage of assembly at minimum. (http://www.appropedia.org/Special:Upload)
3. 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.

1. Estimate your costs
2. Find a commercial equivalent, cite it and put the [url in square brackets]
3. 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]].
