Great print. Love the detail.
Even though it says it doesn't need supports, I found it did. Only on the center fin to keep it in place until it is attached later in the printing process. The first time I tried printing without the support, the center fin kept getting knocked over or falling over. Once I added the support, it printed just fine.
I found in my printing that it needed supports just for the center fin to keep it from falling over while being printed.
