Here are some images that give a closer look at the nozzle design and manufacture. I’m using a regular Ender 3 to print it. You’ll notice that I did a few tests for the threading to make sure it worked how I wanted it to with the 3 inch NPT thread on the PVC pipe.

Below you’ll see the assembled parts, including the individual nozzles, before and after painting.

Some of the nozzles were from a previous print, which is why they are different colors of PLA. In the end, I have various nozzle diameters, which gives each water stream a different size and distance. This adds variety to the fountain spray pattern.

Beyond the nozzle, you may want to see the entire assembly before deploying it in the water.

The frame is aluminum, with stainless steel nuts and bolts, including lock washers. I use a single stretch of pressure treated pine fence slat to mount the electronics and hold the main 3 inch pipe in place. I purchased all the hardware at home depot, and the waterproof electronic enclosures on Amazon. The LED flood lights were also an amazon purchase.

Not shown is the 4 inch PVC tubing I glued together in a square. The aluminum frame is designed to seat into the PVC float, and the PVC float was chosen because it won’t degrade over time in the water. This model was deployed a year and a half ago and has worked flawlessly since then.

This is when we were deploying it. You can see the 4 inch PVC float in the back of the boat.

Here’s a Sunday afternoon row around my pond showing the fountain going in the background.
