My thought was to keep your 'axle' and your bent linkage separate. This way, you can
glue the axle to your plastic.
You leave some space at the linkage end, to slip one side of a double coupler to it. Now you attach the other end of set screw coupler to your bent rod.
This way, the axis of the shutter and the continuation of it are adjustable and can separate.
Your Axle of each shutter can then be
glued good, with no worry about linkage position, it can be rotated and locked into place as needed.
The coupler would be like a small bit of round hollow aluminum, with a 2 set screws, one towards each end, to lock upon the steel rod.
Set Screw Shaft Couplers
Like this but you can make your own or find them cheap?
Hence, micro size decoupling "Smart shutter axle thing..."

My reference theory
Picture an anti-sway bar. Now picture the straight center of it versus the bends that mount it. You want to be able to rotate the 2 of them independently but lock them at correct spot.
Decoupled for off road use, coupled for on road stability. American Axle calls it a Smart Bar.
