.stl intersecting faces
Hey philip.wright9Z
Are you working with a mesh in F360, or are you working with BReps and trying to get a usable STL out of it?
F360 is definitely not intended to be a mesh modeling tool. It has some mesh tools to help with certain applications, but solid modeling and t-splines is what it's made for. I would recommend either re-modeling the mesh from scratch or (if it makes sense in your particular case) going through the conversion process described here:
What software are you checking the stl in? Simplify3d doesn't see any problems, I tried high and medium for refinement of the mesh. I've attached your file as well, in the future can you export and upload the f3d file. The download links are a time waste. How are you exporting the STL?

Thanks for the responses.
We built the model from scratch in Fusion 360 and exported to .stl via the "Make 3D Print" function (high mesh refinement).
When I look via the 3D Hub upload tool there are intersecting faces. However, when I do not include Fillet24 in the model there are no intersecting faces. See images.
I have two concerns:
1) Will it print OK with a commercial printer? The component prints fine with the school's UPBox. However, we need a few hundred of these for a project. I have read that intersecting faces can produce unexpected results with commercial runs.
2) I would like to know why this is happening anyway, so we are not adopting poor practise which may compound into larger errors in the future!

@philip.wright9ZCEG Sorry didn't scroll up far enough before.
Just looked at your STL in Rhino and it doesn't report any errors either. You might want to try using the medium setting for export depending on the resolution of the 3d printer.

Don't think I'd go lower than medium, should be more than good enough for most FDM printers. You could try starting with the medium setting then select custom and set the surface deviation to 0.01.
I think the fault is with the website software. Not sure how 3d Hub really works, does whoever gets the job have any direct contacted or feed back to you? From what I'm seeing with your file the slicer software should not have any problem.
If they come back and want to charge for fixing the model I'd be suspicious they're finding problems that aren't there to get more money.
