A decorative butterfly best printed in multi-colour using something like the Prusa MMU2. Printed in 2D, a crease line enables a slight fold to set the perfect wing-angle.
Printed as shown, it has a 4cm wing span.
Best printed with an 0.4mm nozzle, 0.15mm layer height (0.2mm first layer).
To fold; position the print with the print-bed (smooth) side facing down, gently crease over a sharp edge such as a metal ruler to obtain the desired angle.
Material selection will effect how far you can bend it without breaking it. I found PLA worked fine for the angles shown in the photos.
