Filament runout sensor - Prusa Bear full upgrade - Titan Aero / Hemera

thingiverse

Remix from the reverse bowden top to hold a runout filament sensor. Useful for Titan Aero or Hemera extruder. The output hole is a little bit tinier than the PTFE tube in order to be drill to the right size of your tube. In my case drilled to 4mm allow the tube to be strongly held without blocking the filament. It works with a classical runout sensor which can be found easily : https://fr.aliexpress.com/item/4000253164602.html It use 2 brass insert to fix the sensor and 2x 25mm M3 screw.
