"Printing holes" makes the model fragile

[HQmacpro 0]

Hi all,

 

I'm trying to print a small box with holes in it.  It seems like the printer is bypassing 1 or 2 levels at the beginning and at the end of the hole.

Any clue on how to fix this ?

Thanks heaps !

That could be an error in the model or the hot end had a clog that cleared itself.  

Load the model, set Cura up, use the "File | Save Project" command to create a 3mf file and post the file here.

Hi there,

Here's the 3mf file/

I have some doubt about the hot end clogging as it happens each time, just before and after the holes

I don't have a definition file for your printer so the file won't open for me as a project.  I did get the model though.  Both MS 3D Builder and Mesh Mixer reported errors but they must be minor.

Here is the repaired model.

When I sliced the model it looked fine.  There were no missing layers.  I mentioned a clog only because it's some thing that can happen.  Until I changed hot ends and the hot end fan my Ender was notorious for clogging about 45 minutes into any print.
