One of the drawers in my Kenmore fridge was held up by a flimsy piece of brittle plastic, which promptly broke. Since the original piece was poorly designed and not a good shape to print anyway, I printed this to snap onto the side of the drawer runner and hold it up. Kind of a kludgy solution, but it doesn't stand out too much visually and might actually be stronger than the original part.

This thing was made with Tinkercad. Edit it online https://tinkercad.com/things/70X2Wwi3m41

The end with the notch goes under the drawer runner, and the other end goes over the shelf above the drawer to hold it up.

If the drawer needs to hold heavy things, you may need more than one (or scale it on the Z axis). I have put quite a bit of weight in a drawer with only one of these and it has held so far, though.
