Raspberry 3b 7 inch Touchscreen cover

thingiverse

Für einen OctroScreen mit Raspberry 3b habe ich ein Gehäuse konstruiert, das zum einen den 7 inchTouchscreen (1024x600 Pixel, "7 inch HDMI Display-H") als auch den Raspberry abdecken soll. Ich habe einen 50mm Lüfter mit eingeplant und einen Ausgang für Kabel, die an den GPIOs angebracht werden können (Enclosure-Plugin für Octopi). Ich habe eine Befestigung eingefügt (grün in CAD Skizze, rot gedruckt), die an ein Regatix-Regalsystem passt, aber auch einfach auf einen Tisch gestellt werden kann. Hier müsst ihr eben improvisieren. Der Halter wird einfach zweimal ausgedruckt (wenn ihn jemand braucht). For an OctroScreen with Raspberry 3b, I designed a housing that should cover both the 7 inch touch screen (1024x600 pixels, "7 inch HDMI Display-H") and the Raspberry. I have planned a 50mm fan and an outlet for cables that can be attached to the GPIOs (enclosure plugin for Octopi). I have included an attachment (green in CAD sketch, red in print) that fits a Regatix shelving system or might be placed on a table. You just have to improvise here. Print part "Halter links" twice. BOM for Enclosure and Raspi Case - 4x press nut M3 length max 6mm, diameter of holes is 3,5mm (a little tight) - 4x metric screw M3x12 - 4x washer for M3 DIN 125 B - 4x M2,5x15 + 4x washer for touchscreen fixation ("Halter" will also be fixed with the 2,5mm screws, if you plan to use it...) - optional: two thin stripes of neoprene (Moosgummi) to fix the backplane to the touchscreen. - touchscreen i used: https://www.aliexpress.com/item/1005001704445373.html BOM for Regatix holder - 1x Regatix wall holder - M8 threaded bolt approx. 200mm - 4 Nuts M8 + 4x washer 8,4mm for fixing bolt to Regatix wall holder - 4 Nuts M8 + 2 x washer for fixinf the holder (1 regular one used as locknut on each side) - 1x Nut M8 for the handwheel (can put it left or right) +1x washer (PA6 as optimum, steel will do) BOM for fan: - 4x M4x16 lens head screw + 4x washer - 4x self locking nut M3 + 4x washer - 50x50mm 5V fan with dupont 2pin connector (to fit to the plug at the touchscreen back) - 1x self locking nut M8 for the end without handwheel + 1x washer Printing: - I used 0,6mm nozzle with PET-G at 235 deg and heatbed temperature of 80 deg. - Try to print the 2,4mm walls using "walls" of your slicer. If using a 0,4 nozzle, you need 3 walls. - use dry filament or you will die in strings ;-) Tip: Some micro USB plugs for the power connection of the Pi are very thick, I lowered the backplane as much as possible and even the thick ones will fit, but maybe there will be no space between the plug an the backplane.
