Raspberry Pi 4B and 7" TouchScreen Enclosure

 

I start from …

I need a case for Raspberry Pi 4B and 7" TouchScreen from Raspberry Pi, to be used as a controlling unit in the home automation system.

Found on Printables, but … 

I try https://www.printables.com/model/53066-raspberry-pi-7-touchscreen-rpi-4b-enclosure-mount which is prepared for mounting on a 3030 extruded aluminum profile. But that model didn't cover my needs. It has some nice features slim screen case, the large case for RPi. What I found difficult was remixing the existing model so I decided to create my own with some improvements and provide some new features. 

My model needs to be … 

I would like to have the model in a format able to improve and change the model, and I support OSI so use FreeCAD.

Additionally, I would like to have an Enclosure that adequately supports all connection points. be easy to print and prepare for 3D printing, be enough strong, and be modular at the same time.

Raspberry Pi Screen dimension I gather from https://datasheets.raspberrypi.com/display/7-inch-display-mechanical-drawing.pdf .

After some testing, I finalize the model and FreeCAD file is available in the download section.

Printing …

No special recommendation, print without any support using PETG, 0.4 nozzle, and 15% of infill.

Assembly Process

Montage RaspberyPi 4B with standard elements to 7" TouchScreen from Raspberry Pi, and connect included wires to Screen board (not to RpI itself) also connect flat cable from Screen board to RPi board.

Place upper connected hardware on top of the reversed side Screen case (shown in the following picture).

Put Screen case over hardware and slide it to place.

Reverse the case and firmly press the screen in the case. You may listen to some soft clicks (depending on the tolerance your 3D printer has). 

Connect 4 wires to RPi GPIOs.

Prepare RPi case by adding 4 M3 nuts to their place on the bottom of the case using Prusa's suggested method of inserting the nut with screw using pressure.

To add the RPi case to the Screen case you will need 4 30xM3 screws (if you would like to use other types of screws you will need a max 7.5 mm clearance outside of the RPi case).

Prepare screws, and slide RPi case from right to left (you will need to implement some pressure because of the tight fit of Network/USB connectors, very depends on 3D printer tolerance ).

When everything is in place screw all 4 screws in place.

For connecting brackets to RPi case you will need 4 12xM3 screws (it is possible to use little longer screws, because of clearance in the RPi case).

The bracket has holes that provide a place for the screwdriver for screwing it.

 

For fixing to wall/cabinet/anywhere else you will need 4mm wood screw at least 16 mm flathead one.
