I've been trying to upload this model for the last couple hours, but Shapeways keeps coming back to me saying 'Sorry, we can't process your model'. I've run it through Netfabb repairs and manual repairs in C4D, I've confirmed it's one shell and the surface is closed, but it won't process the damn model. Plus, this model is EXTREMELY similar to another model I uploaded several days ago - all I've done is change the orientation of the pendant 'hole'. I've uploaded it to this post, but will be taking it down as soon as my problem is resolved. EDIT: Removed, problem identified. EDIT: I also wasn't sure which forum to post this in, so took my best guess.
