Only exporting exterior faces into Cura

usb holder.skp (287.7 KB)

I’ve been trying to export this model into Cura, but it seems to only be seeing the external faces when i rotate it to minimize the need for supports.

Cura is also generating a “roof” on the top of the box.

Any help would be greatly appreciated.
I’m a beginner with sketchup and cura so please be patient with me. Thanks.

There’s an internal face that prevents the component from being considered a solid.

After fixing it, I uploaded it to iMaterialise and it seems to work fine there.

Try fixing the component and see if you still get the same results.

I fixed that face, but its still looks like this in Cura… aka Its not seeing the inside faces of the “walls”

I don’t think it’s your model. Have you checked with the Cura people to see if they have an idea?

Not sure if this matters but what if you rotate the box in SketchUp so its open side is up?

ok. Yeah i’ll have a go with them.

No, I tried that as well.

Thank you for your help :slight_smile:

It would be interesting to know what you find out.

Another thought comes to mind. Is my STL file different from yours?

No, it looks the same to me.

doing the same thing with the infill

Did you hear anything from the Cura people about this?

no, not yet. Nobody’s replied
