Found this photo online of an Italian style doorknocker which is very common on old houses I guess in Italy. So, I had this one lying around for some time and thought maybe someone would like to have it printed :) In all honesty: I've tried to make the ring moveable but haven't succeeded...yet.
Let me know if you would want a fully functional one, I can give it a try ;-)
I've printed this one on my UP! Mini with a layerheight of 0.2mm and loos filling. Print it on it's back and it will come out nicely! As I said before, it's not functional on this moment, more of a decorative piece. I did leave enought room in the "mouth" area for the ring to move, but I haven't dared to move the ring hard enough to break it free :P
I think if you would paint this with some metallic paint and "age" it, you will have a nice piece for the house ;-)
