Nikon HB-32 Lens Hood - Remix

Use whatever print setting you think are appropriate for your desired quality.  The slower you go the more likely you are to get a really accurate result.  I did mine in PLA at about ⅓ the default speeds settings for the Anycubic Kobra 2 in Prusaslicer.

No supports or brim is required if you print it with the thread face flush to the print plate.
