Hello, I am a first time 3D designer and printer. I have a teacup I designed in Google Sketchup (see attached file). The teacup, when exported to a DAE file, is accepted by Shapeways when I upload it. However, before I print it in white glossy ceramic I wanted to get some feedback. Do you see any issues with the model that might lead to unexpected results upon printing? Thanks in advance for your help!
