This project was created as a support for a STEM Challenge. The nozzle was created for an aquaponics and hydroponics setup in a classroom. The nozzles of the original pump were 0.51in and 0.62in. The teacher only had an 1/4" interior diameter tubing, which was too small for the original nozzles. There was also a design idea to provide a split of two lines of tubing to water the plants. Sketchup was used to model the part, mimicking the main threads. The top was modified to provide two 1/4" nozzles.

This should print without supports, but on some printers it might be necessary. One thing to consider is that after a print the two 1/4" nozzles might need some clearing of the print material. Also the 1/4" tubing did fit snugly on the nozzle and didn't not fit down past the first cone shape. It was adequate for pump operation for this need. Feel free to modify if needed.
