I tried mounting my Ergodox EZ to my chair like you (almost exactly too: 3D printed mount + gorillapod). I found the TRRS cable between the halves to be very very annoying to get in and out of the chair. How did you solve that problem? I once tripped and broke the mount (PLA is brittle) when I went to answer my intercom.
I bought a long TRRS cable and ran it behind the chair.
d'oh?!

That’s fantastic. Is your 3D model on Thingiverse or anywhere else? I’ve been thinking about making exactly the same thing to use tripod mounts on the Moonlander.
Here you go: https://www.thingiverse.com/thing:4769654/files
Honestly, I measured the hole spacing as 19.5mm but it is definitely not quite right because it is tough to get all 4 screws in. I don't have gauge pins to measure it correctly, and the accuracy suffers. But you can get two screws in which was enough for my use.
I uploaded the Fusion 360 file so you can easily correct this.
I would also print it upside down from how it displays on Thingiverse. That way the mount <-> keyboard interface is as smooth as possible. (Well, if you have a smooth print plate, I guess.)
I did eventually get parts for both sides. One of the flexible arm clamp tripod mount thingies was not stiff enough to hold the keyboard up, but the other one was great. Since they were both the same part from the same order... it's kind of a crapshoot as to whether or not it will work. But I will continue to experiment.
