Looking at making this diff cover. It is similar to the one in the picture. I am working in sheet metal because I want to cut the entire dome piece out on a cnc plasma cutter then bend it with my finger brake press.
The Issue i am having is filling in the gaps. I know they all need to be flanges so i can properly unfolt it, but can't get a flange to stretch the complex geometry.
Should I try designing this in another way such as in models?
