Problem in exporting Rhino model

Hi,

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!


detail.3dm (1.5 MB)

Thanks

Hello - I’m not sure what you are running into - here’s what I get (from one ‘unit’)

Test.stl (1.0 MB)

Thanks very much. Your file works perfectly fine!!! I restarted the system and now I get the same result as yours.

Thanks for your time
