Ender 3 Automatic shutdown (+Source Inventor)

This will let the nozzle head hit the switch and turn off the printer.
Make sure to use wire and a switch who can handle the load!
Also since this is AC I recommend switching both + and - wires, and connecting the earth together. Also the switch holder doesn't have a cable hole, so put the cables tough it before soldering them!

======
0.2mm tolerance pre-set

======
'Switch_Holder' is for mount it to the X as itself (you lose 2cm of your bed) use 'X200' to hit the switch
'Switch Holder X' is for mounting over the X as-tensioner, adjust the X end code as needed (I think it needs to be X220 or something)
'Switch Holder X V3' is for mounting with an X belt tensioner (https://www.thingiverse.com/thing:2986144) offset is 'X235' so only 1mm of the printing area is lost [BEST SOLUTION]

======
Needed:
- 2x M3 bolt and T nut
- Switch "8553vb" from "Arcolectric"
