Just out of curosity, I downloaded this file. It's a pretty detailed piece. I removed the base, resized it to 4.5" wide and looked at it in Shapeways. To print the model it would only cost about $75, I just think it's amazing. I've sent a message to the artist and with their permission I'll see how well it comes out in Shapeways. I won't do anything else until I get the permission from them.
