Box for 7 inch Touch screen +3 switchs + Raspberry PI4, to run Octoprint

My target was to create a box covering all wires arround a 7 inch touch screen, a raspberry PI4, and 3 switchs.
Only one cable is reaching the box with an USB connection to the printer, a power input for the PI, and some switchs lines. A Raspberry camera is also connected using a flat cable.
So the box can be moved easily and the touch screen is very easy to use and to run the printer through Octoprint.
At the rear, a 40*40mm Noctua fan is also connected to the PI4 , keeping the temperature of the PI4 below 50°C even after 24H+ prints. So the system is realy reliable (not as the PiZero connected to the main board with a camera...)

Print instructions

You can print without supports with PETG or PLA.
To close the box (see pict 5), I used 4 M3 inserts on the top cover. The screws to be inserted at the back cover, can be : 2 M310 (for the small width) + 2 M318 (for the large width).
The screws to fix the screen from the back should be carefully calibrated to keep enough space between the back of the screen and the screws (see pict 6). I used 4 M3*18, but please be carefull not to damage the screen with too long screws.
Some other screws M3 have to be used to fix the fan, the feet, the cable fixation system. You can screw them directly to the holes (as I did), or if you wish, you can use inserts if you beleive that you'll need them.
The switchs I used, needed a 19.5mm circular hole to be inserted.
