Ender 3 Microswitch Bracket

Decided to add a auto shut off to my ender so I Don't have to monitor it and know it will shut off safely.
I also have a BLINK MINI camera set up so I can tune in and watch if I need to. I also have the power unit hooked up to a WIFI PLUG incase I need to shut it down remotely if I am away.

This works amazing and happy with how it all turned out.. yes there are simpler options, but this is by far the safest.
