BTT Filament runout sensor for Direct Drive Ender 3

This is a mount solution for the BTT Filament Runout Sensor when you have installed a Direct Drive Kit.

I combined the roller assembly from https://www.thingiverse.com/thing:3052488 with my own mounting solution on the X Mount plate.

To Install, simply remove two screws from the BTT and replace with M3*16 ones through the mounting plate, then use 2 or 3 M3 screws and bolts to mount it to the X-Axis where the extruder used to be.

You must use a Bowden tube so the sensor works correctly; see pictures.

There is also a mount without the roller if you don't want to use it.

I have used it for over two years, and it's still strong.
