Abstract

1. 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

1. Appropriate feedstock for printer - be aware that some plastics like PLA absorb water readily
2. 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
3. Upload and link to all STLs

Tools needed for fabrication of the OSAT

1. MOST Delta RepRap or similar RepRap 3-D printer
2. 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

1. 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.
2. Include print time estimate
3. Include assembly time estimate
4. Including drawings or pictures of the device at stage of assembly at minimum. (http://www.appropedia.org/Special:Upload)
5. 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
3. 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.

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]].
