To go along with another flower I created a while back (see link below), here are voronoi calla lily flowers.  There are two versions varying the hole size.  They are very delicate!  And I used very thin supports.  When I printed it, I slowed the printer down to “silent” mode.  If you want to print faster, I recommend altering the custom “tree support” setting back to their original values.  I did add some custom supports to the bottom for a bigger base to help prevent them from coming detached from the bed.
