I have no idea why I can’t export this file to STL format for 3d printing.
I used to do it without a problem with the default setting. (below images)
Can someone point out where the problem is?
The model is a simple form. When I export it to STL, it’s around 330 Mb!! After I import it to Cura, I see the below image!
