This shelf support doubling as hinge and lock for the top two hatches / doors on my very old freezer broke, so go print a new one :-)
(It was also an educational project for learning Fusion 360)

The Freezer is a Blomberg FS3101 which i think was only marketed in Scandinavia, but anyway, in case it can help anyone.

I was considering whether the PLA would become brittle in the freezer at -15 deg C, but It's now more than four years ago I printed and installed the new parts, and they still appear fine and work perfectly.
