G’Day all,
I have had numerous requests for the STL files of late so I have decided to post them on here. The are free to use by anyone for personal use. If you want to use them commercially, please let me know.
They do cause some drag but I have tried to minimise that with these designs. I also did look at making them to fit between the original nosecone and the main body of the thruster but I wanted to maximise the deflection. A square face to the direction of the water flow only captures the weed against the guard blocking water flow. By taking the grill angle out to the nose tends to push the weed to the side rather than building up in front.
Anyhow, enjoy and I am open to design suggestions/alterations.
