Thats the biggest problem on Shapeways in my opinion. Your services are not regular for a peny :twisted: I hope u can make something to explain them that they can't say me that my models are rejected when i already sold this particular model a lot of time !!! The more funny in this is that i just have to reupload the same model again and by the way 90% of the time you print it without any problem ... I already know your answer but i dont agree, this is a non-sense... You print a model , then you reject it, then without any modification you print it again and again and again ... then you reject it !! then without modification you print it again and again !! Each time you reject a model the mistake is the same. By the way if you mesure an edge on a model you can always find a smaller value if you take your mesure more on the top of the edge ! so thats easy to reject any model ... I think that a system to confirm models and make them directly printable without verification would be awesome !
