Ender 3 v3 SE Filament Run-out Swivel

I've mounted my spool above my printer and I've used the mounting holes for the factory spool mount to create a swiveling mount to allow atleast some movement in the sensor.

I'm not sure how actually useful this is compared to a static mount, but it was fun making.

The mounting holes for the sensors are Ø2.9mm (M3 bolt) and CC 20mm, I just screwed into the plastic, you can use a nut if you'd like.

You may have to experiment with the printing orientation and use a little force to break free the ball after printing.

The mount on the printer are Ø6mm and CC 20mm, if you're using it for something else.
