About this 3D model
This is a decoration for your personal christmas tree. Just print it and pin it to your tree as you like it. ;) I created the dxf from a picture using vectorization with InkScape. Then I just imported the dxf into OpenScad to extrude it. That's it! You may see this thing as inspiration: http://www.thingiverse.com/thing:8692 Merry Christmas everyone! ;)
