Abstract
Many developing third-world countries have a steady or increasing need for clean drinking water. Many solutions for achieving clean drinking water already exist, but require expensive manufacturing equipment outside the area where there is a need, and then incur shipping charges to ship them to the target location. 3D printing technologies allow rapid manufacture of humanitarian-aid devices such as water purification tools. This printable design requires some filament (preferable ABS), a tea bag, and activated carbon to create. This allows the user to drink filtered water on-demand from and standard plastic water or pop bottle.

Costs
The activated carbon was obtained by cutting open a $6 Breta water filter (if bought in a six pack for $24) from Walmart. the carbon from one filter was able to fill 12 tea bags, making the carbon cost per bag $0.50. Activated carbon may likely be found cheaper than by using this method.
Tea bags are available from Walmart in 100-count boxes for $3.50, yielding a unit price of $0.04 if rounded up.
Cura estimates both parts will cost $0.51 to print.
Total cost: $0.50 + $0.04 + $0.51 = $1.05
Tools needed for fabrication of the OSAT
- MOST Delta RepRap or similar RepRap 3-D printer
- No other tools!
Technical Specifications and Assembly Instructions
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]

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]].
