One of the most annoying things about the Artillery Genius 3D printer is that it keeps running after the print is finished, with its fan making noise all night long until you get up to turn it off.

With this assembly, when a print is finished and the bed moves to the max of its axis, it will push on a wire that conveniently pushes on the shutdown button, turning off the printer.

2 minor drawbacks : 

• If the switch is toggled a bit early before the bed movement ends, the printer will show a message saying that print didn't finish on next startup (just needs to press ok). Maybe it's not good for the usb drive, but I've been running that switch for years without any trouble
• If you have a print that needs to print on the last 10mm or so of the bed, this switch will turn off the printer mid print^^. In this case, you'll need to bend the wire a bit to disable the switch before starting

Material : 

• About 650mm of wire strong enough to not be bent too easily. I used 3mm diameter, and the hole is sized a 4.25mm. FreeCAD file is included if you want to change some dimensions
• Just reuse the screws that are already on the printer to bolt the prints

To bend the wire, i'd recommend using a vice, really convenient to make it super straight. And don't forget to slide in the prints before bending it ;)
