Housing for cabinet ventilation control

This is the housing for the LCD, rotary-encoder, Arduino Nano, a circuit board with some small components and a LM2596S DC-DC converter. The completely control unit is powered at a 24V port of the Printers PSU and stepped down to 12V with the LM2596S.The controller sets the fan speed of an 120mm fan, wich is mounted to the cabinet with my mountThe housing is mounted to the cabinet with the holder, it can be found her: https://www.printables.com/de/model/162912-holder-for-cabinet-ventilation-controlOn my GitHub you can find the code for the Arduino and the schematic, the PCB design and the code for the Arduino. If you need a PCB i have some, so you can contact me.
