Accessories to Go into Kegerator Shelving Slots

Has anyone seen cool accessories (either commercial or DIY) that people have done with the shelving slots inside of a lot of the mini-fridge Kegerators? I have a Danby and since a lot of times I have at least one side occupied by a 2.5G keg, there’s some dead space up towards the top of the fridge near the slots where the wire shelves can be slid in.

I was thinking there might be some cool gadgets or DIY solutions for using this space (e.g. holders for cans, bottles or chilled glasses), but Google is failing me.

Has anyone seen anything like this before?
