These are the best! I'm having one problem printing them out. The pieces come out looking beautiful - such a nice design. But the neck of my turtle's head does not fit into the tracks for it on the shell or the bottom piece. The necks are too fat. I'm new at this and my printer is an inexpensive entry level 3D printer, so I'm guessing its an issue with my fun, but cheap printer. I'm going to try increasing the size of the shells and bottom to see if I can get the neck to slide in. The head is big enough looking I think, that it won't look out of scale to a bigger shell.
