Problematic STL Output

[Anonymous]

Hey folks, I've go the following drawing:

And when I export to STL and try to 3D print, it crashes my slicer (Cura-Lulzbot). If I open the STL file in SketchUp, I can see why; it's a mess, there are faces missing everywhere:

I couldn't find any STL export options or preferences, so I have no idea how to modify this. The shape is a solid, so I'm not doing anything weird with walls or anything. 

Anyone have any ideas? DWG and STL attached.

Hi Bryan,

I opened your STL file in Rhino and I don't see any missing faces - the model looks solid:

Interesting. I opened it up in xcode's STL viewer and it looked fine in there, too. 

I wonder why it's failing to look right in SketchUp and why it's causing my slicer to crash. 😐

Sigh....

Have you reached out to LulzBot support yet https://www.lulzbot.com/support

Yeah. They're the ones that tipped me off to the slicer crashing being a problem with the STL.

Now I'm leaning towards this being a bug in whatever STL parsing code the slicer and probably SketchUp uses. 😐

Most likely.
