Long time ago I wanted to make a realy nice monarch butterfly.  The butterfly was printed with PLA 1.75 mm (GD Filament). As I uploaded the colored 3mf file - you can simply swatch the colors as per your wish and simply print it - you dont need the re-color the model. Use different colors, as I did - see the pictures. For hanging the butterfly around I used some of the clips models available and glue it to the butterfly. No need of any support. After printing you can use a hot-gun to give different shape to the butterfly wings, which will give more realistic view to your model. You can download as well the stl file - if you want to make your own color design.

I upload repaired model. There was a gap between colored and black layer. Thank you BO3DE for noticed it!

Happy 3D printing!
