These gears control the cold / hot air input to AC in C4 Picasso (2006 - 2013, not tested on > 2014 ).
Original ones are kinda weak and always break around the hex where the servo is attached.
This is a quick design with a reinforced servo attachment. The "guide post" is a bit flimsy but it works (if broken when installing use some drops of instant glue)

It takes around 90 minutes to print
