how to print a hole with "union overlapping volumes" ON

[Minkeproducts 3]

Dear All on the forum,

Would anybody be at help for the following? I would like to print a mesh with a cutted hole inside (the model is good, watertight and so on) There is a setting in Mesh Fixes, stating "union overlapping volumes". I would like to have this ON (for another reason). If I turn the model, I can print it fine; wíth the cutted hole (see image 1)

If I print the model in the preferred position, I have a problem printing the hole with this setting ON (see image 2). The hole gets visible again with the setting "union overlapping volumes" OFF (see image 3)

 

The reason why I would like to print it with this setting ON, is because I use an external program to make support (in Meshmixer) and therefore the complete print will print at its best.

Maybe there are suggestions that helps me out?

At this moment I print this models in the position as image 1 (with the hole horizontal), but I would prefer to be able to print the hole vertical as well.

I found the solution for this problem by double checking the models; The cutted hole had a manifold part of faces, caused by the cut and these faces should have been the other way around. Now, Cura reads the cutted hole as indeed a part of the model and I can print it wíth this hole, no matter what position.
