I just received this model from Shapeways: http://www.shapeways.com/model/930854/super-mario-mobius-und erworld.html As you can see, the model is colored on all sides. I followed the instructions on how to submit a model for color printing in sandstone, which is why it appears colored on their site. However, upon receiving the physical model, it is missing half of its color! See the pictures. Any help/suggestions?
