SKR Mini E3 V2 case Remix

Remix to the great case made by MrTeliP. I added a slot on the left side for the z-stop cable, or the ABL cable. I added a 45 degree angle slot on the back so that you don't have to remove your cables to install the board into the case. I did the angle so once the cables drop in they will move to the left and stay in the opening instead of popping back out. Hope you like the new features.
