Fridge shelf for various manufacturers

A Fridge Tray that may fit into your fridge, because the same dowel form has been used by differernt manufacturers. To my knowledge AEG, Zanussi, 

To check if this fits into your fridge compare the look of your tray with that of the model.

To print:

Print outof any material suited, pay attention, that the overhangs are all supported, especially the joining parts. You may need to post process the edges for it to fit together before you glue them.
