Stainless steel small double torsion springs

These are 2 small double torsion springs made of stainless steel 304. The first spring (the one on the right) is easier, while the second spring (the one on the left) is a lot harder to be made because there are a lot of right angle bendings, and these bendings are made in a small space. We spent almost 2 days to program the machine.
