I see now, thanks.
It’s not a bug with 3D you found, really, but a bug with Strokes and the way they are shown and later treated by 3D.
Take a look at the video attached.When a live stroke gets processed by the 3D effect, it gets outlined. We can see what the effect sees by applying Outline Stroke to the thick green stroke. Once we do it, we are able to see how incredibly messy it really is — and this it exactly what gets inflated.
If you change the Corner Join type from Miter to Round — no problems occur.See, you apply a rather large stroke to a rather thin object... the stroke has two edges, and while one gets offset fine, the inner one is condensed and twisted by the Bezier math.
I personally would have used a different approach to avoid this altogether — see the .ai file also and the image.
Instead of strokes I’d use fills and apply Offset Path to each one. Plus I’d remove black fills from the original art inside of the group (but it makes no difference here, since the 3D produces a raster image in the end, but will guarantee cleaner results for vector artwork).Anyway, this is an interesting finding! Illustrator seems to hide the tangled result, exposed by 3D and Outline Stroke, but perhaps it should not. Thanks for sharing this!

I can’t really understand what’s missing based on the screenshot, sorry!
Can you provide a test file with the object included, to test the problem?
