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

prusaprinters

<p>My target was to create a box covering all wires arround a 7 inch touch screen, a raspberry PI4, and 3 switchs.<br/> 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.<br/> So the box can be moved easily and the touch screen is very easy to use and to run the printer through Octoprint.<br/> 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...)</p> <h3>Print instructions</h3><p>You can print without supports with PETG or PLA.<br/> 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 M3<em>10 (for the small width) + 2 M3</em>18 (for the large width).<br/> 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.<br/> 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.<br/> The switchs I used, needed a 19.5mm circular hole to be inserted.</p>
