Nice rig! 
Great work with the door, much better than my fridgador. It's my old fridge, and slightly smaller than yours. I have to boast a little bit regarding the pre-work. I cleaned it like I've never cleaned anything else in my whole life. 
6 treatments with detergent, and 4 with clean water. The last stunt I did before I start using it was 6 weeks with a bowl of vinegar water, and the door a little bit open. Quite honestly I didn't have too much to put in it at that time 
The next 3 months I put in an electronic humidifier, an extra hygrometer, 4 cedar trays and 1,5 pounds of 70%Rh Heartfelt Humidity Beads. The last upgrade I've done was removing the icebox. There is not much use for the elecronic humidifier, since I had problems to get the Fridgadoor down to 70%Rh. I started to use it about a year ago. By now it's app. 50% filled, rock steady at 70% and temp +/- 3 degrees round 65 F summer and winter. For some unknown reason it takes much less refilling of the beads than the beads in my one year old Cuban Crafters Elegancia humi.It's another brand (Cigar Mechanic 70%RH) I'm quite pleased with the Fridgador. U gave some ideas with that door, I have do something before I have filled the rest of it up.
My next project is to buy a decent 300 sticks humidor for aging, and a tiny little one for my infusing project, and.... etc, etc. I'm a real stupid SOB, should have started the Big Adventure about cigars many years ago.
I really enjoying every little aspect regarding cigars. Lucky me, I also get a slight hangover if I smoke over 3 sticks a day. Makes it a little bit easier to control the big animal in my stomack (read ex smoker...) I'm trying to hold my consumpton to 3 sticks/week, but U know; -some days U just slipping
