Freezer Shelf Corner Replacement

Replacement for the missing corner pieces in my fridge's door shelf. Two of these, one flipped, will fit over the studs in my 2001 Frigidaire refrigerator. Add a strap between the two corners, and voila! You can use that door shelf again.

* v4 - (final version) moved horizontal bar attachment out a bit to accommodate more shelf space; added some slopes to try to minimize material without requiring more support material.
* v3 - flipped and modified design to require less support material.
