Hi! Im making an iPhone case and I've been looking at a few here on Shapeways and I saw that some people were mixing up the depth and the height. For example, one case was made with the dimensions: cm: 8.446 w x 1.384 d x 11.898 h and another was made with cm: 8.446 w x 11.816 d x 1.142 h. What should the depth be? A high number or a low number? Thank you!
