From what I can see, the overhangs don’t look too dramatic — it’s a lovely design.

I did a print (9hrs!) but my NACS adapter has a fatter ring that prevents it from latching on the little nub in there.
I found a 3d model of a NACS plug. So I'll try to modify it to add the fatter ring that mine has and then see if I can use it to subtract the necessary space from this wall mount.
