Would be nice to have the Ctrl-E config export.

Works after a pass through Netfabb's online service. I wonder what it did that caused it to render properly.

The config file.
Also I tried the same model in Cura 3.0.3 - it was able to slice it just fine, if that helps.

Cura tries to do more with file repair than Slic3r does, so that doesn't
mean much.
As I noted, Slic3r does just fine after the model gets a pass through
netfabb. I will have to try to compare what Slic3r thinks the model looks
like with both versions. The fixed version is also larger iirc.
Currently I am leaning towards GIGO, but the input code needs to be looked
at to make sure there isn't a bug in it.

Self-intersecting faces.
That "missing" area mesh isn't properly connected to the posts. There are 10 shells that are all individually manifold.
Here's a picture after applying split:

Okay, that makes sense, it's the first time I tried to use FreeCAD to model something, and apparently I did something wrong. Thanks for the help1

@lordofhyphens which tool did you use to figure that out?
jdevelop
on 4 Nov 2017
Meshlab with the face view turned on showed a line going right through one of the pegs.
It also has a "show self-intersecting faces" feature.
In FreeCAD you want to do a boolean union on all of the components and extract the resulting mesh, IIRC.

I regrouped the model a bit, so now it exports just fine. So at least I know - if something doesn't slice from the STL/OBJ exported by FreeCAD, and looks _okay_ after fixing the mesh - it's likely that the model itself is broken.
Thanks a lot again :)

No problem. Happens a lot; solid 3D modeling is surprisingly finicky. One of the reasons that most things out of Sketchup are garbage (and by extension 95% of models on Thingiverse are garbage until proven otherwise ;) )
