About this 3D model

I created a koopa shell that is printed in two halves to make the print easier. When I created the model I made it upright so each half will have to be rotated (One 90 degrees in the y-axis and the other 270 degrees in the y-axis) Apparently the autogenerated image isn't going to appear for this object so I included at screen shot of one half from repitar host slicer.
