I have got a simple model of stacked boxes and I intend to print it in 3d.
So I made a boolean union and exported a stl. Thing is that when I open and check the file, it has about 432 non manifold edges.
I then delete these edges but the result is a mesh full of holes. The been trying the commands recommended to solve these issues, but dont, the mesh holes are too big and too many,
Any ideas on how can I solve this?
