Brick Case Screen (BTT PiTFT 70) (Patreon)

This is now fully usable, and a few tweaks, now support for both heat inserts (4.6 and 5mm OD) increased the screen hold depth by 1mm so should be more flush

There is a braket that shifts the pi to leave room for the usb cables

To secure the Pi and bracket you'll need M2.5x6 or M2.5x8

Screw and heat inserts are totally optional for the actual case and even screen, this can hold on it's own as is, just sliding the pieces together, and screen can just rest there (as long as there is no risk of it falling off a table).
But if you want it secured or super secured the option is there. you can use magnets on the top.
Can be super secured (not very easily) and be completely lock down, with two not easily accessible  screws that secure the backplate to the top.

To secure the screen you'll need M2.5x6 (or maybe m2.5x8)

One screw hole is missing on purpose on the bracket as that screw would otherwise be under the GPIO and could risk an electric short.

Connect to the Pi via ribbon cable, included with screen (all in one power, display and touch)

I was able to fit power, ethernet and usb without needed angled version of them.

Meant to be used with the klipperscreen project 

You can control multiple printer with just the one screen+pi over the network.

No print support needed, print everything vertically.

I included an stl with the 3 pieces arranged so that it can be printed in one go (except for the pi bracket)

This was 2 walls, and 5% gyroid  infill - about 225g of filament, does feel lightweight but sturdy enough for this.
if you want to to be sturdier increase the wall and infill

One fan is likely enough, has a spot for a 4010 or 4020 fan (would recommend noctua 4020 with PWM, which you can control through the pi GPIO, and bit of tinkering some info here, the PWM frequency is "wrong" in that project, should be closer to 20~24Khz, but I don't know if the pi is capable of that high frequency via GPIO, but regardless can likely work even at lower PWM frequency. )
