For my testing I used Matterhackers Silver PETG filament (250C on the FLSunQQs), and for my settings I have attached my Cura screenshots. I made it with a flat base so it was easier to print, but a few supports will be needed. I used the experimental tree supports in Cura because they tend to be easier to break off, but you have to be carefull around the fingers.
I printed at 90% of the original file size to decrease the printing time to 11hrs 11min, but you can always decrease the layer height for more detail (it just takes much longer). I printed at .25mm layer height.
