I needed to relocate my electronics since I have ordered a thermal tent for my Ender 5. I didn't want the works to be fouled up in the heat so I went looking for a remote box to house the LCD and Raspberry Pi. Found MANY useful designs but nothing really had everything I wanted in one place. So I Frankenstein'd my own creation... enjoy.
This box works for either Pi 3/3B or Pi 4B (See images)
Two part box with overhang latches. Cutouts on the right side for full size HDMI cables and USB-C or Micro USB power. Cutout in back for passing ribbon cable off the LCD screen. Plenty of venting for passive cooling.
Both Top and Bottom will print without supports. Some cleanup may be necessary for long overhangs but it still works well. Print the TOP upside down on it's face to avoid any need for support material. Print the BOTTOM right side up.
I used 4 M3x5 screws to secure the Pi to the base. Predrill your holes to make it easier.
I used the stock mount screws for the LCD (M3x6 I think) so predrill those holes also.
