That driver of all decisions and action - a deadline (supercon) is coming up so ... progress happened!  Bought into the hype and bought a bambu printer to iterate the mechanical design.  I'll join the many other voices saying they're worth the hype - this is the first printer I've bought that *just works*.  Completely redesigned the mechanism for attaching the display, it's now a friction fit flat taper that extends about an inch above the top of the frontend.  I hadn't tried them in plastic before, but with a little iteration and some post-processing with a file I'm *very* happy with the result.  Clicks together and locks well without any additional mechanical parts or clips or anything.  Might add a clip of some kind and work on getting it to fit right off the printer but happy with it for now.  

I don't love the smaller switches or where they are, but liked alternatives less.  I'll have to incorporate more of the front panel design into the next one.  Making the electronics a little smaller should also give me a some leeway there.  I do like the look of this a lot better than the previous one though.  

I'll do a more complete post and release of everything, and video, after supercon, I'm happy enough with the state of everything to publish at this point. 

I do need to make a rev 2 of the board eventually (and a rev 1 for the display section!) to cut down the size and reduce the point-to-point wiring, but sticking with the same one for the moment, again just to get something good enough out the door.
