A&E Bird Cage Drawer Restraint

When I purchased my 61"x32"x23" A&E bird cage, I was surprised to discover that the bottom drawer (the one that catches food and droppings) would suddenly fall right out of the cage when pulled more than about half way out.  The design flaw is that the top support for the drawer ends about half way along the drawer.  I designed and printed these to prevent the drawer from falling out.  My cost to print them at home is reasonable (perhaps a few dollars); the cost to print them on Shapeways is higher, and may not be cost effective.  Note that you will need either 2 or 4 of these fixtures for them to be effective.
