This mount attaches a 12mm inductive sensor to the stock 40mm hotend fan. It's probably the easiest way to attach one to the Sunhokey I3.
(In case someone wants to know which x carriage I'm using: it's this one http://www.thingiverse.com/thing:900225
Note: the MKS Gen boards have HARDWARE pullups and therefore you need a sensor that pulls the signal pin LOW when triggered. I had one that is active high (Part number: LJ12A3-4-Z/BY) and therefore I had to add a MOSFET/BJT inverter...
The LJ12A3-4-Z/BX should output a LOW when triggered and therefore be more convenient to use with the Sunhokey board since it is normally open (NO) and has an NPN transistor built in.
