4/2 != 2

Small progress, but still something. link 4 almost done, - just copy, rotate and flange to connect with link 3. But it's not finished yet, so small update. I skipped part of geometry, which i think will be hard to flatten, and even harder to assemble. It might happen that this part (area where link 5 rotates) will have to be changed, but that will be known after link 5 is completed.

Best,

K.
