I had another model rejected yesterday. Again, a model that has printed successfully at least 30 times.
The rejection is based on wire minimums. According to the design guidelines:
How to design thin, unsupported wires:
"0.3mm-0.6mm wire thickness: keep under 6mm wire length"

Here I have .44mm wires supported at multiple points. True, the supporting points are closer to 6.6mm apart, however this should still be well within the acceptable tolerance, ESPECIALLY for a model with a numerous printable history.
(At least I would consider about 30 prints to be numerous
)
Here are some photos of one of my successful prints. The same photos that accompany the model on the product page:

Careful observers will notice the railing for the ladder is broken. More careful observers will notice the thickness for the railing parts are thinner than the ladder. And further yet, clever observers will notice that in the rejection photo above I had thickened the railings to match the ladder. Finally, I'll admit that it was me that broke those railings during cleaning
But notice that the overall ladder assembly is printed PERFECTLY.
I think the best test should be, does the product have accompanying photos of a successful print?
Then why perform the manual check? Shouldn't that be sufficient proof?
Additionally, this model was ordered and printed more than a dozen times! THAT, should be definitive proof.
