This was made in order to make the hotbed cable connector safer.
There were some cases of printers like this catching on fire and i believe that this mod could help a little bit.
If you are using the original Anet`s Auto Leveling Sensor, its a good idea to move it to the front of your hotend, it may hit the cable relief in very large prints.
I mixed both source files using Fusion 360.
As a noob, it was the easiest way of doing this.
