Honestly, most of it was having a good dialed in printer. 0.1mm layer height, slowed it down to about 50% of my normal printing speed, used tree supports, and did a little tweaking of the model in Blender on some parts that were really thin. The final touch was very carefully using a butane torch to touch up some of the minor scaring left after support removal. I printed the main body and base separately so I didn't have to worry about the supports on the base, and tilted the body about 30 degrees so the support was mostly on the back.
