It seems like almost any STL file I import becomes corrupt except for very simple ones.
I can print the orig file. If I import it, it “repairs geometry”.
When I inspect it, it is corrupt. If I export it I need to send it to model repair to be able to print it.
Why does importing mess it up? Do I need a diff importer?
