Feather Ring i designed as a gift for my little sister, I've got it printed in silver with antique finish through shapeways and came out fantastic. The feather was designed with Fusion360 and then shaped to a ring with Blender. I've attached the DXF flat drawing of the feather, the .blend file with all modifiers not applied so you can tweak them, and of course the stl file. Size should be 6 but you can resize it in to appropriately fit your size.
