I have a self intersecting object that I want to clean up for 3d printing. As far as I know you cant have a self intersecting object, but correct me if I am wrong.

I have tried splitting the object far away from the intersection and then using the intersect command. For some reason that didnt give me an intersection all the way around so I had to take the objects and delete the surfaces that the intersection line did show up and play around with it to get the rest of the intersection. I tried using that line to trim, split and anything I could think of, but it all failed.

I also tried taking the objects after I had split far from the intersection and boolean them together. This also failed.

I have attached a file with the following for easy checking:

Layer name Contains

1 solid self intersecting object

split line the line I used to split the object into 2 so I could use intersect

Intersection resulting intersection line after using intersect command a few times

2 objects the 2 objects after I split them with the split line

Thank you for any help you can provide.
