The PCB and components look good and feels sturdy. I would prefer a white PCB for the white case :)
Some of the screws are in a awkward location where you need to remove the screw to take out the switch. M2 screws might be better for these tight spaces, for the next revision.
The case is very nicely printed and feels nice and sturdy. Unfortunately a corner chipped off during shipping, but the keeb.io team and the shipping insurance took care of it swiftly. I was very happy with how the issue was resolved.
Some standoffs for the PCB and the plate would be nice.
