Ender 3 Filament Runout Sensor for Lack enclosure

This is sort of a remix of Filament Runout Sensor w/ Creality Limit Switch by 3djpco - Thingiverse and Ender 3 / Pro Filament Runout Sensor using Limit Switch by nandogommez - Thingiverse

I used both before but the little spacer that you glue onto the z stop sensor kept falling off - so I remade this from scratch in Fusion 360 so that the filament runs directly against the sensor and there's no need for the spacer

Printed in PLA, 20% infill

I used supports on bed but it prints fine without them
