This is an induction sensor for the Anet a8 3d printer. The mount uses the screws of the extruder fan so all you really need to do is print it out and install it. The is the very last thing to go on the screw so the fan cage goes on before it. It may be a little tight to start with however everything goes on eventually. I will be making another version of this as this was made just to get me started with autolevelling.
