We have an internal so-called "sanity check" which proves that model is not super small relative to the bounding box size. The default sanity check coefficient for AM is 2% (model volume should be >=2% of bounding box volume) and 10% for CNC (model volume should be >=10% of bounding box volume). But depending on the type of models you typically get, it may be wise to lower that setting.

If you want to lower your setting, please go to Widget settings, Topology recognition:

and change the setting. The same model should now pass:

We hope this helps :-)
