I got a new A8 that has tighter clearance around the buttons. The old button trim was too large and since the buttons taper, I can't get any clearance at the back of the Button faceplate. So, I made a shallow trim to keep the buttons straight when I push them. The trim just pushes on over the buttons.

For Version 1 with larger clearance:
