HallON v3 - Anet A8 backmount

Mount for extruder back of Anet A8.

Required parts:

• Hallon V3 sensor
• 2x M4 bolts
• 1x M3 bolt to lock sensor in mount

Parts to print:

• mirrored Hallon V3 base case (to switch button on the other side - form the https://www.thingiverse.com/thing:4576488 )
• modifed button for Hallon V3 (in files)
• mount for sensor (in files)

Firmware settings:

• NOZZLE_TO_PROBE_OFFSET { 19, 45, -10 } (last one Z you must calibrate by yourself)
• PROBING_MARGIN 40

Warning! Do not switch the polarity of the magnet pins, as the sensor will not work properly! Be careful when installing the magnet in your new button, test it to be sure.

I made this becuse I have mod to opening extruder ( https://www.thingiverse.com/thing:2249215 ) and I can't install sensor as creator advice. But its not perfect because you have to set "PROBING_MARGIN 40" and in conseqntion probing area not reaching directly edge of table. Moving Y endstop further should regain some area space, but I didn't made this at the moment.

I advice 100% infill for mount and regular (20%) for button.

To install mount you have to mage thread in bearing holder. I used just M4 bolt by slowly screw and unscrew bolt. Ofcourse using screw-tap will be easer :). You can mount this using longer bolts from the extruder side but I broke this part so many time that may by inconvenient options in that cases.
