can you please tell me what is the problem?
thank you

It means it ran out of memory making the mesh. I don’t know what sort of settings you used, the model seems okay here. Use the manual Mesh command to create your mesh first with reasonable settings before export.

Thank you for your reply. Please can you tell me how to use the manual mesh command in this case to get reasonable setting?

is that good?! the unit is millimeters

Sure? There’s no 3D printing technology that needs accuracy of 0.001mm.

i am not sure, it is for Jewell!
