E30 Condor Pull Strap backing

The Condor Pull Strap comes with rosettes that clip into the Condor door cards. I want to use them with my own carbon fiber door cards and I want the strap to also help hold the door card in place.
So I made these things to screw the strap onto the outside of the door card and then the Condor rosettes slide on the front of these.
The driver's side includes an opening for the mirror control switch. If your car is European you'll need to flip this file.
