Fridge Door Bar Holder/End Cap
Update: Added a version with rounded edges. The sharp edges of the original are not hand friendly.
The clips on the door bar holders/end caps in my fridge broke. This is what I came up with to replace them. My fridge is from the Crosley brand, but it looks like the part can be found in Whirlpool, Amana, Jenn Air, Kenmore, Magic Chef, Maytag, and possibly other brands.
