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 its millions of other uses.
This OSAT is a garden hose splitter that can be used to split water streams from a common garden hose nozzle. This splitter can be customized to any desired size, and can be paired with multiples of itself to further increase splitage.
No special skills necessary, just use of a 3D printer.

Modify the .scad file to use your hose type (GHS or BSP).
Slice the file using your favorite slicer.

Print the part.
Apply tape or adhesive material to threading to create good connection.
The cheapest I found was $8.99, although it also had valves. But chances are you can get around not having valves. So cost saving is like $6.50 per unit. That is a 620% saving!
Leaks at the hose connection
Cause: The wrong thread standard was printed.
Fix: Make sure you check what sort of hose you will be using. If you are in the US it is most likely a GHS, outside of the US it is BSP.
