Abstract
- Paragraph description of the OSAT - why is it Appropriate? What need does it fulfil? Are there case studies you have found of a technology being used successfully?
- Picture of completed print using your printer
Bill of Materials
- Provide a full BOM -- Materials needed for fabrication of device and alternative materials if they are not available, prices/sources of non-printable parts
- 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
Skills and Knowledge Necessary to Make the OSAT
- If you used special skill – link to relevant wikipedia or wikiversity articles/courses
Technical Specifications and Assembly Instructions
- 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
- 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]].

Abstract
Conserving water is becoming more of an important issue in today's world. An open-sourced sprinkler attachment for a hose can lead to less consumption of water. Its main use is providing a low cost irrigation solution for small gardens. Urban farming specifically can greatly benefit from an open-sourced sprinkler attachment.
Bill of Materials
- 3D Printer
- 1.75mm diameter PLA (1kg ~ $25)
- .STL file
- Hose
- Water Supply
Tools needed for fabrication of the OSAT
- MOST Delta RepRap or similar RepRap 3-D printer
Skills and Knowledge Necessary to Make the OSAT
Basic understanding of 3D printing
Technical Specifications and Assembly Instructions
- Download the STL file
- Generate gcode via Cura, Slicer or another slicing software
- Print the sprinkler head using the 3D printer
- Screw the sprinkler head onto the water hose threads
- Turn on water supply once sprinkler head is placed in desired area
- Assembly time estimate: under 1min
Common Problems and Solutions
When printing the sprinkler head, set the infill high enough to eliminate unwanted leaking or spraying. Also ensure that the printer is extruding at the correct rate.
Cost savings
- Commercial Equivalent: $5-$20 https://www.google.com/search?q=sprinkler+head&safe=off&es_sm=93&biw=1920&bih=955&tbm=shop&source=lnms&sa=X&ei=6fl_VNfhGcyqyAT2r4HABg&ved=0CAgQ_AUoAQ&dpr=1#spd=16760520700473328747
- Sprinkler Head: 33grams of PLA at $25/kg ---> $0.83
- Percent Savings (using low end commercial equivalent): 83.4%
