hello ganchan,
the next batch will not have the imperfection on the lexan , it concern just the laser cut .
the flex you see is because i screw a bit too much , the lexan is like a thick sticker , i can cut the holes in 4mm or more .
on the metal panel ,
the leds and buttons holes will be 4mm instead of 3 and 3,5mm , and window 1mm bigger.
in this case it's impossible to see the panel after lexan fixed .
pics very soon .
