I got the connectors from Aliexpres:

I will likely have 4-6 spares when I am done that I am happy to drop in the mail.

Here is the pinout I came up with. It is not exactly how Ian describes it (at least how I read it) because looking into a male connector, the pin numbers snake back and forth (unlike a d-sub connector):

Top left pin 1 (looking into male connector)
1...15
30...16
31...45
60...46
