Tree structure not supporting small areas entirely leads to filled print

[Nissaba 0]

Hello. I printer a model and 2 location it as some small areas that need support and the tree structure only provided for a bout 1/3 of the width that surface leaving the rest to air print. I am attaching image and model if any one wanted to take a look.

This is a model that really should be 3 or 4 separate pieces that would be glued together.  As a single print, it's tough.

The STL file is "not watertight" and the errors in the file can effect the way Cura sees it and slices it.

When first imported the bottom of the model is not flat on the build surface.  Use the rotation tool to "lay flat".

When a feature starts over support, and is very fine, then you need to keep playing with the settings until you get the minimum XY right, the XY overrides Z, or Z overrides XY, Minimum Interface Area, (etc.) correct for what you are trying to do.

This is an image of the first layer that appears for that hanging feature of the model.  You can see that the settings are correct to provide support and an interface to hold the start of the print...barely.

 

  

 

The attached 3mf file contains a repaired model.  Pay close attention to the ALL the settings as they are what I like and may not be what you like.
