I remixed CdnReprap's awesome Pi case (Pi 2/3) to add a broader base, a 4010 cooling fan, and updated it for the Raspberry Pi 4b I use for OctoPrint, but especially OctoScreen. This is one for the Raspberry Pi Touch Screen, and may not work with the knockoffs.

It might also work for the B+,2B,3B,3A+,3B+, but you may need to manually expand the ports.

Due to the usb port on my screen, I had to add more than 8 mm of depth, yielding about 3 mm clearance between the boards. If you use other hardware, make sure you have enough clearance. You can peek in the cooling slots to check clearance.

Print with open side down and with supports, 4 walls, with at least 50% infill. Alternately, you may be able to print at an angle, using less supports and print faster.

You'll need 4 - M3 x 12 mm screws to fasten the screen to the case. I removed the standoffs from the screen and used the small screws that came with it to attach the screen controller to the screen. I also used two M3 washers as those screws were a little too long.

It's easy to damage the screen by over-tightening the case screws. If you lightly tighten the case screw while watching the screen (while powered) and see white spot in the area of the screws, they're too tight or too long. If they're too long, add a few washers.

I had to flip my screen as it was up-side down:

In Terminal:

sudo nano /boot/config.txt

Add line:

lcd_rotate=2

To exit:

Ctrl + X

Y

Enter

sudo reboot

Update 12/30/2021: Added a version without the base, intended for mounting to a rail or flat surface. Hole pattern is 60 mm x 30 mm x M3. Time permitting, I'll be adding a mount to attach it to a V-slot.

Update 01/01/2022: Added v-slot mount. You can I mounted it to the frame with up to 3 M3 screws using T-nut M3 drop-in rotating V-Slot by DaVinci2000.

Added top corner mount and flat mount, again with 60 mm x 30 mm x M3 hole pattern.
