Hi Dick,
It looks like you intend the PCB to go over the lip of the front of the base plate and screw to it. Any chance of doing the same on the sides? Might you put threaded holes along the sides for that purpose? The PCB would be more securely held along those sides and, more important to some applications, there would be better thermal conductivity from that part of the PCB to the frame of the box. You might also be able to eliminate some of the stand-off's which would allow more of the PCB for components.
Another thought, which might not be compatible with the first thought... I see that the box lid has "ears" that come down over the front (connector) plate and a screw through each of them. Any chance of reversing that and having the ears on the front plate with a screw through the cover from the side? That would help with space for connectors on the front plate a little.
Looking good!
Chuck

Attached are three pdf views of the proposed revised Eagle module, and open view, fully closed view, and a view w/o the PCB. It has been a lengthy day getting all of the darned 0.5mm cover bends correct and holes properly placed for full mating of the cover with the baseplate (such things as 0.581mm hole placement discrepancies – ugh!). If built from the drawings that can be made from these objects, there should be a good fit in the real hardware.
I do not presume as to what the “real” next step wants to be, as I do not propose to make the 2D drawings until the discussions have settled down to agree that this is what we collectively like, or at least collectively accept. Please advise.
