DIY Klipper box with OLED display and rotary encoder

I made a cost-effective Klipper box that has an OLED display, a rotary encoder, and a push-button power switch. It was specifically built for my Ender 3 V3 SE to run Klipper, but it could be used in any Klipper system that needs it.
OLED display needed to be converted to be used with I2C instead of SPI, and I also had to prepare a piece of 4-pin flat cable with Dupont connectors.
Together with Raspberry Pi Zero 2 as a Klipper host, everything fits together inside a custom designed 3D printed housing, and I have shown you the whole process, from preparing and wiring each of the components, to Klipper installation and settings adjustments, and to how each components are configured in the system.

Components used in the project:
OLED display: 2.42in SSD1309 with SPI and I2C capable interface
Rotary encoder: KY-040 type
Power switch: 12mm tact switch with button cap
Raspberry Pi Zero 2

Tools and materials:
4-wire flat cable, M2.5x4mm screws, Dupont connectos, crimping tool, Soldering iron and solder
