Got my plate last night. Feels heavy and solid. It was a good idea to flip the DWG file around so that top could be sanded. There were a lot less metal shavings and debris compared to my TKL plate, so it's ready to have switches dropped in without having to file the inside cuts. Here's a few other comments:
Top shot of the full plate.
Details and surface came out pretty nice.
The bottom of the plate as these blow-out marks on every cutout. You can sand these out yourself, but it's the bottom so it doesn't matter.
There's a noticeable bend to the plate. Since the plate is so stiff, you will probably have to unbend it, otherwise it might flex the PCB or put pressure on the standoff/screws if you try to screw it down anyways.
I put it on the edge of the table and pushed down, opposite of the bend, and 5 minutes later it's flat again.
