Hello, I am trying to help my student upload this project to shapeways in order to print. So far I've tried the Meshlab, and Netfabb suggestions for repairing and preparing for upload. I've done whatever I could and understand and still they won't except my file??? It does say that I have 6 shells? Is that too much for a solid file? And if so how can I make it so it's one shell? Attached is the file, please let me know if you know a solution for me. My student needs to order this week in order to hand it in for his 8th grade project. You can see his blog here: http://jonascreations.wordpress.com Thanks!!
