You could always cut the appropriate places in a QFR top. I have done one like that, but I still need to paint it.
Yeah, I'm leaning that direction, just not sure how clean I can get the lines. Still, I have a QFR I kind of want to put into a different case, so maybe that would make sense. Use the QFR case with cuts for the Phantom.
Plum 96 maybe?
This looked promising, but the non-typical shape of the PCB makes me leery.
