Ender 3 Case Control Board MKS Gen L with 4988 steppers - Raspberry Pi 3B - LM2596

I was searching for a control box to fit my MKS GEN L, Raspberry Pi 3B and a Buck Convertor (LM2596). Plus, I wanted to be able to still easily connect a usb cable to both the MKS GEN L and the Raspberry Pi.
I did not find such a box, so I decided to create it on my own as my very first fusion360 project. While I was at it, I decided to incorporate a cable chain connection for the heated bed. It replaces the cableChain_40MountSide from the cable chain at https://www.thingiverse.com/thing:292006
