I was pushing out the strips of metal on the vase last week. I made a pusher out of delrin and a file handle.
Pushing the things out went ok.
Folding did not go so well.
There are certain edges I need to trim down a bit so the piece fits together better. I need to cut about 1mm off about half the edges. The piece is not very rigid because it is pierced everywhere, so trimming these edges will take a while. I haven't worked on the piece since this point. I was annoyed about the extra work I will have to do, and I have some other things I need to do, so this vase can wait.
