How about this:
https://www.partmaster.co.uk/fridge-freezer/fab30lpk5-si00/universal-fridge-bottle-wine-rack-shelf/product.pl?pid=4673603&shop=smeg&path=253462&refine=bottle+rack&model_ref=14691242
From a quick look, the model is FAB30L, and the latter bit is the colour, so...
PK5 = pink
OR5 = orange
RD5 = red
...so you probably won't find a wine rack that specifically says FAB30LPK5, but any FAB30L accessory should be fine.
Are one of these any good...
