Elecrow 7" Display-D Case

A basic case/housing for the Elecrow 7" Display-D. It currently fits my needs, but I will add another backside without an attached Raspberry Pi 4. Maybe made modular so you can optionally attach the Pi in a separate Housing to it. A tilted stand will be added soon.

The pins to access the buttons on the display have a small tolerance, but they should sit tight. If needed, use some sandpaper. 🙂

Stuff that you need:

• 4 x M3 x 30 (35 works aswell)

• 4 x M3 x 4 x 5 threaded inserts

• HDMI cable (30 cm)

• USB-A to USB-C cable (30 cm)

• Raspberry Pi 4

• Power Supply

No specific print settings required. I used PLA (Prusament Galaxy Black) as the Pi 4 doesn't get too hot. You'll need to print the pin 5 times. Use atleast 5-6 walls (sfaes time). Printing of all parts took approx. 4.5 hours on a BL A1.

Assembly:

• Screw the Pi 4 to the display with the provided studs

• Wire everything up

• Clean the display beforehand

• Use a soldering iron and carefully melt the threaded inserts in place (use a cutting knife and make sure they are sitting flush without a bulge! This is important!)

• Put it in the front bezel (tight fit, correct orientation)

• Make sure the circuit board of the display sits flush

• Place the 5 pins accordingly

• Put the front bezel onto the rear cover (don't push down on table!)

• Align carefully, fit 2 screws from below while holding up (yes, it's fiddly)

• Don't forget the power cable

• Turn around and screw everything tight

• Enjoy!
