Garden Hose Stream Diffuser or Intake Filter Attachment

This fits on a standard garden hose. If placed on the outflow, it disrupts the stream of water so you don't disturb your soil (I use it for filling fish tanks where I don't want to disturb the substrate). If placed on the inflow, it stops larger objects from being sucked into the hose. 

While the threads are designed to spec, I don't recommend cranking them too tight, especially with a brittle filament like PLA. 

Note that if you plan on leaving this outside, you might want to use a UV-resistant filament like ABS or PETG. 

Overhangs and stringing on this model are a bit tough, but I found that dry filament and proper cooling (especially leaving the door open if you have an enclosed printer) works well. Make sure you have your wall order set to do inner walls before the outer wall.
