This is simple holder for inductive sensor and fan for auto bed leveling on Anet A6 printer.
I now have this on my printer and almost operational. A few more tweaks and I should be there. When it's done i will publish the .stl files
This is intended for an 18mm sensor: LJC18A3-H-Z/BX Approach Sensor Cylindrical Capacitive Proximity Switch NPN 6-36V
It is somewhat larger than many people use. If you need another dimensions of the 18mm sensor i can add one with the correct hole size.
In some cases keep in mind that you have to make change to the x-axis limit switch
because the sensor holder will hit the left end of the printer before the limit switch does.

The only other thing you need to do is to set the z-offset after flashing.
