Abstract

Water is one of the most important aspects of life all over the world, arguably the most important. So it is critical to have a robust infrastructure that can handle the demands of water, whether they be for survival, or agriculture or it's million of other uses.

So for this project I build a simple garden hose splitter. [1]

1. This OSAT is a garden hose splitter that can be used to split water streams from a common garden hose nozzel. ^[1]. This splitter can be customized to any desired size, and can be paired with multiples of itself to further increase splitage.

Bill of Materials

1. PLA/ABS
2. Garden hoses
3. Water seal/ moldable plastic

1. 1. Source files and stl files can be found here: http://www.thingiverse.com/thing:571542

Tools needed for fabrication of the OSAT

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

Skills and Knowledge Necessary to Make the Splitter

• No special skills necessary, just use of a 3D printer.

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. Download part off thingiverse.
3. Modify .scad file to use your hose type
   1. US: "garden hose thread", which is 3/4" straight thread and a pitch of 11.5 TPI (male part has an outer diameter of 1 1⁄16 inches (26.99 mm)) and is used for 1/2", 5/8", and 3/4" hoses
   2. Non-US: Outside the United States, the more common BSP standard is used, which is 3/4" and 14 TPI (male part OD is 26.441 mm or 1.04 in)
4. Slice file using your favorite slicer.
5. Print part
6. Apply tape or adhesive material to threading to create good connection

It takes about two and a half hours to print if using 50% infill.

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