Spray bottle cap replacement

Here's a replacement spray bottle nozzle cap.

My cap was very similar to a Glass Packing Institute (GPI) 28-400 dimensions, but my newbness in Fusion360 is so extreme I couldn't figure out how to model the threads exactly. I used the thread modeling tool and made a set of threads that fit well enough.

I printed mine at .20 resolution in the current orientation with supports only on the bed. It printed ok. Best thread quality may call for full supports. Do what your printer needs for optimal quality. If printing again I'd use .15 layer height.
