I was missing a filament sensor on my Ender 3 Pro, and I had the Awesome Filament sensor from MapleLeafMakers on my V0, so decided to remix it, and make it more universal.

A Big Credit to Andre!

BOM :

• Omron D2F-L (Important it's an L! = Lever piece)
• wire
• jst-xh plug or similar (depends on your Mainboard)
• 2x m2x10 self tapping screws
• 1x 6x3mm magnet
• 2x m3x8 BHCS
• 2x m3 t-nuts
• a little heat shrink
• a solder iron (soldering the wires to the switch)

I cannot provide any useful configuration for Marlin, as i run klipper on my machines.
