Just been dealing with a difficult model. It was showing as non-manifold in the 3D Hubs but it looked like it would print anyway initially. In future I think I should just not accept an order until it is shown as OK in the print-ability report.
Question for 3D Hubs: does turning down an order which is showing as having print-ability issues affect my stats negatively in any way? Obviously it shouldn't do, but the question is does it? The problem is if I accept the order and then have issues (As I have done here- maybe foolishly), that can lead to more negative feedback and a lot of stress for the hub trying to print something that has already been deemed unprintable.
What is your advice on how to handle printability issues?
