Replacement Door Shelf Bracket for Sub Zero Fridge

Having had broken and missing shelves in our older model Sub Zero since we moved into the house 22 years ago, one of my main goals when I bought an X1 Carbon was to engineer and print replacements for these shelves, since the replacement parts for this 1980-vintage Sub Zero were long gone and would have been absolutely stupid expensive if they were even still available. The existing shelves were cheap plastic and ugly metal that were all broken in some form and looked really cheesy and bad. The fridge needed a total of three - two in the refrigerator section that were broken and one in the freezer that was missing, and they are all interchangeable so the same design would work for all of them. My thought on replacements were to duplicate the keyslot design on the originals to engage the existing rails in the door, but to widen and double the amount of teeth (from 2 per end cap to 4 per end cap), add much more thickness to the base plates and replace the hideous front panels with some .
