A Low Poly Feather originally created for my sons's shield from the series of books, “Beast Quest”.

the model was scaled to around 120% in Prusa Slicer.

In the photos it has been lightly sanded and primed white then painted to look like a Phoenix Feather (not book accurate but he likes the flames). I then heated it gently with a heat gun and poked it until it cooled down to give it some relief.
