I needed a larger bezel for my car as it has two single DIN frames (rather than a double DIN). I made this with a larger bottom edge to hide the gap, it fits snugly around the AX1000, AX3000/AX3200 and AX5000 screen. I curved it to match the interior of the car, and I've included the f3d file for you to make modifications if required.

Updated 15/08/2023: v5 now has flat chamfered edges rather than the curved filleted edge, and I also centred the double DIN hole.

Please also advise if you've used this on another double DIN headunit and it has or hasn't fit.
