Abstract
- Spigots manufactured for self-attachment typically rely on large gaskets to maintain a seal, which works with varying success on the curved surface of a bucket. By modeling a bucket with just its top and bottom diameters and its average thickness, it's easy to design a spigot with contours that fit well. This design is expected to fit a wide range of bucket sizes effectively. The main attachment is reasonably easy to print, and typical modification requires changing only 4 parameters in two files.

Bill of Materials
- Appropriate feedstock for printer - be aware that some plastics like PLA absorb water readily
- Will likely require a gasket of some sort between outer section and bucket - 3.5cm gasket or flat rubber cut to size will probably be sufficient
- Upload and link to all STLs
Tools needed for fabrication of the OSAT
- MOST Delta RepRap or similar RepRap 3-D printer
- Tools necessary to make 3.5cm hole in bucket
Skills and Knowledge Necessary to Make the OSAT
- Need to know top and bottom outer diameters of bucket, average thickness of bucket, and desired height of spigot - scripts will do the rest, assuming no other changes to geometry
- Useful site for bucket dimensions: [1]
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
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: [2]

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:Water use]].
