The rack was $9 from The Container Store. It is called the 3 shelf spice rack. I used double sided sticky tape underneath the screws to support the weight. The surface of the inside of the door is very thin. Be sure to drill large enough pilot holes and countersink them slightly larger than the threads of the screws. Also, use soap on the screw to help prevent cracking. The entire project took 10 minutes and about $10. The space between the inside of the door and the actual useable space in the fridge is totally wasted and available.
