This fitting is made to be an alternative to an airstone in a RDWC hydroponic setup and works with a 16mm OD garden hose.
Printing:
There is a flat surface at the bottom to lay the part onto in the slicer and keep the barbs level with the bed. having the layers aligned with the barbed part helps keep it together when you push it in a pipe or pull it out.
Aside from the bottom of the barbs being a bit rough this prints well in both PLA and PETG, though the latter will probably be better for prolonged use, and it's what my current nozzles are made from
Post processing:
The barbs print ok generally, but the bottom part with contacts the bed will likely need a bit of cutting and/or sanding.
These leak. Superglue works well enough to seal them, but I wouldn't bother except with especially leaky areas that might reduce flow through the rest of the nozzle, as you do need some velocity.
Usage:
Keep your pump output clean. The small diameter of the outlet makes these clogs easily.
Cleaning is as easy as pulling the nozzle out and injecting some water through either end with a garden hose.
I'm currently using 6 of those with a 1300 L/H pump and it seems to be doing fine, but with a smaller pump or more nozzles you may wish to narrow down the openings.
