A8 Anet Auto level sensor holder

I installed this auto level sensor because I know it is very important to have the first layer well printed to have a fixed base. I designed new fixation method because the others are fixed at the top of the fan, I prefer to fix it in between the radiator and fan. This is also good to serve as spacers to avoid pressing thefan onto the radiator.

Use a LJ18A3-8-Z/BX (18mm diameter - 8mm distance) or a LJ12A3-4-Z/BX (12 mm diameter - 4mm distance) sensor
Connect the Blue wire to the – of the Z
