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?
When using a composting toilet, it is common practice to separate urine from feces. This reduces the smell and pathogens that are present in the toilet. Excess moisture in the toilet creates an anaerobic environment which promotes the growth of smelly bacteria. The goal of this project is to produce a diverter that can be used on a 5 gallon bucket style toilet. Current models range in price from around $10-40 which is very expensive for a developing community.
Bill of Materials
The CAD model and STL can be found at MyMiniFactory or Thingiverse
1X 5mm flexible plastic tubing or equivalent
1X hose clamp or zip tie
Tools needed for fabrication of the OSAT
- MOST Delta RepRap or similar RepRap 3-D printer
Skills and Knowledge Necessary to Make the OSAT
This print is very basic and requires no supports. It may require a brim to reduce warping.
Technical Specifications and Assembly Instructions
To assemble, simply press the tube onto the barb and use a hose clamp or zip tie to secure it in place.
Common Problems and Solutions
The most common problems with this design would be issues with print adhesion and other common printing problems.
Cost savings
This device is designed to replace much more expensive diverters that are commercially available. This diverter is one that is commercially available. It is $50.77.
This design can be printed for under $1
14 ft of tubing can be had for $13
200 zip ties are about $4
This means that this design is 65% cheaper than the alternative. The spare parts are also very useful and can be used for many different things besides this tool.
