Body produces non-manifold edges

autocadFH8KR — Tue, 16 Sep 2025 14:56:58 GMT

In the attached project, I have exported the Component "Hoocho Tower Base Planter" as an STL file.

When I import that file into 3D slicers (BambuLab Studio, OrcaSlicer) there is a complaint that the body contains non-mainfold edges. Need help understaning how this occurs, and especially how to correct for it in Fusion.

Your problem is here where you have more than 2 surfaces sharing an edge.

If you edit this extrude and make it 2 sided and extrude 0.1mm down so you get an overlap it should work.

After changing this I get a good mesh when imported into Fusion.

EDIT. Note this still leaves a very thin section that might be a problem for printing.

Oh, I see your suggestion now. Thanks, will give that a try.

Thanks for your attention; BambuStudio and OrcaSlicer are now happy with it. I will accept the solution and revisit if it doesn't print properly.
