Indentation Won't Print on Model

[ewatson 0]

The attached model has a 6.35 mm circular indentation that won't print on the UM3E when facing down.  I haven't tried to print in inverted (indentation on top) but would like to avoid that solution (not to say it would even work) since it will require additional supports, etc.

The problem is with the model's normals. You can fix this in Cura by installing the mesh tools plugin from the marketplace, selecting the model and then using the extensions -> mesh tools -> fix model normals menu item. Hope this helps.

Is it though? I was under the impression that CuraEngine completely ignores normals. But if MeshTools fixes it that's cool.

Thank you so much burtoogle... your solution worked well.  I don't want to get into the weeds, but what is meant by the "model normals".

 

Thank you!

Sorry, I'm not really the right person to answer that, here's some general info https://en.wikipedia.org/wiki/Normal_(geometry)
