Interpretation of STL file very different

Hi there, I have spent quite some time to design this friisbee model and wanted to get it to a 3D print service. The upload of the file then showed a strange outcome. Can you help. I am a bit concerned.image


If you open it in different viewer, is it OK?

You can experiment with adjusting the STL export quality.

István, it has nothing to do with the resolution quality. I don‘t have a different viewer. I can send you the file Shapr3D file for you to repeat.

I tested medium quality which provides a correct form but which is far too rough and high quality which creates this awkward erroneous form.

Yes : Could you please send the file to so we can check it?

Thank you really much!
