3D printing issue using an .STL file

[ProutPet]

Hey, i have made a model, and given it a 2mm thickness for 3d printing. While setting for printing, the print supports are protruding through the mesh itself, I’ve set my print support to 0.05mm and still the same issue is happening. I am not if it’s the issue with me model of the software. Can someone please help?

I’m no expert in 3D-printing… but it seems the printing software puts you object somehow slanted…

I wonder why??

Also it seems the SW doesn’t “find” the correct connections points because the supporting tubes are… to0 big (diameter ) ??

Also looking at your blend with the 3D-print addon…
