Peugeot Heating Arm

Wanted to replace the 3 broken light bulbs in the heating system of my sons his Peugeot 206+. By dismounting the system, due to the rigid stainless steel cable to regulate the temperature of the heating, the regulation arm broke at the end. So I tried to repair with some metal and glue the broken part. But trying to reinstall it in the car the small retainer part broke again. So I decided to reverse engineer the part in Fusion 360.
