Raspberry Pi "Pro" Case

This is a case for a Raspberry Pi 2/3 (RPi 4 not tested).
During a CPU test with sysbench, the temperature did not exceed 31°C (16°C room temperature) and the fan is hardly noticeable when its spinning. Im using this system for home automation, but it is used for other applications as well.

Experimental Status:
This case was designed to make a housing for all my components for home automation.
Maybe some day there will be a tutorial on how to assemble and manage the Raspberry.
There are many aspects which I would change in a future version.
Until that, I would recommend this thing to people who already have a basic knowledge in 3D Printing and also have the skills for the programming.
But if you do have questions, feel free to ask.

The case can hold a 80 mm Noctua fan, a motion sensor, a 0.9 inch Oled display, original Raspberry Camera and a 11.5 mm cutout for the power IN. After installing all of the electrical components, theres still room for more sensors, relays, etc.
In the shown pictures you can see, that I hot-glued in a 2-CH relay, a DHT22 and a DC-DC converter to power the fan and raspberry simultaneously.

4x M5 screws with 34-60 mm thread length
4x M5 screws with 9-23 mm thread length
4x M2.5 screws for mounting the RPi to the base mount
3x M4 screws for mounting the base mount to the back panel
8x M5 nuts

I recommend adjusting the holes for the screwing nuts for some thinner screws (M4), because it was very hard to screw the M5 Bolts through the noctua fan.
Also, if you want to print the case, you should think about creating a better mechanism to hold the back/front/left/right pieces together.

The mounting base for the Pi is available from this link:

It can be screwed on the "back"-panel
