Holes pattern in curved and planar surfaces to stl : Self intersecting surfaces detected.

andrea_rossi972

Hi guys,
I am trying to create a basket for a watch washing machine.
I need all the vertical walls covered with holes about 1.2 mm each.
I used 2 techniques
On the curved surfaces, I created new solids and then I used a circular pattern along the perimeter with remove attribute.
On flat inner surfaces, I used the fill pattern feature script
The problem is that both methods give me a self-intersecting structure and I am unable to 3d print the model correctly.
can someone point me to where my mistake is?
Thank you very much

Andrea

So your slicer is warning you about self intersecting geometry?  If so, most slicers have options allowing you to instruct the system on how to deal with self intersecting geometry.

Thank you for answering me. Maybe I solved it. I changed the slicing software switching from simplify3d to cura.
Cura doesn't detect any problem with the model and the slicing procedure went smoothly. I am printing the part right now and seems fine.
