Assembled PCB with the display module screwed and connected :
The casing is made of two laser-cut metal plates. They are both 4 mm thick and made of stainless 304 steel.
The metal spacers are 20 mm high. The reference used here is 970200471 from Würth Elektronik.

Fully assembled console :
The hatch is made of PCB FR4. The hatch does not require to be as strong as the console casing and the FR4 is a good material to cut complex shapes into.
The hatch is cut as a PCB panel containing all the required parts :
The first assembly step is to glue the hinges :
The second step is to screw the sliding part, and also the bolt used to manipulate the hatch slider :
There is not enough room to use Nyloc nuts, so normal nuts are used and held in place with threadlocker.
The tightening of these bolts allows the slider to slide with a little force, so the hatch can't open alone.
The strike is made of a piece of PCB coming from the panel edge that is inserted by force between the two metal plates :
Now the hatch can be assembled onto the console.
