Tiny IR Filament Sensor

Hi !
This is a 1st version of my filament sensor. I use those cheap infrared sensor from ebay.
Overall, it's just a housing that goes around it, letting you pass the filament inside. You may add a part of PTFE inside for better result

The PTFE tube may need to be trimmed to fit inside the sensor. Like that the only visible part between the IR will be 1.75mm

Printed with a .25mm nozzle
Maybe it's printable with a 0.4, didn't try it

You will need
2x M3x10mm screw
2x M3 Nut
