A new filament sensor much more reliable than the "old" optical laser sensor. The sensor works mechanical and hence is independent of optical properties of the filament.
The upgrade kit allows installation on the new the new Prusa extruder body. It works as well on Caribou extruder bodies with the following housing:
another possibility is the installation on a Bontech extruder.
