It would be superb if I had all that room to work with, but this build uses a vertical adapter. I have max of 0.125 currently and could probably stretch that to a bit wider connector with some more milling, say 0.200. The only connectors I have found that are close to working are board mound rather than surface mound, unless I want to build a connector housing for these.
I have made some tabs yet to be installed that will hold the wires in their intended place during assembly. So, that will have to be sufficient to keep the wire straight while the unconstrained length is (tugged) into place.
