T4 (Multivan, Caravelle, Transporter) double cup mount/holder

The model is still a prototype that I am testing in my car.

Replacement of the heater fan grille with a cup holder adapter. The dimensions are pretty tight, so it's better to take out all the grilles, insert the replacement and then put everything back.

The important thing is to remove the clip from the left side of one grille and use that for the new holder. The clip will ensure that the ring does not break.

Be careful not to damage anything.

Then just slide the cup holder in and you're done.
