Neotibicen or Dogday Cicada wings
Print with high/fine resolution (.12mm) - only takes about 45min
No infill
No adhesion
No support
I kept shell thickness around .5mm to keep the solid portion smooth, might have better options here.

may come out with some thin scrap lines easily removed with a thin blade. Don't sweat some other printing defects, nature is imperfect. This has some fragile/flexible parts but should peel easily if you let the plate cool and start on the thick side.

Frankly pictures don't quite do the 3D detail justice.
