Runout sensor housing & Filament roller

thingiverse

This is a remix of my filament roller, thing 4835184, to include an integrated filament runout sensor using a redundant Z-stop switch. Everyone who installs a BL Touch will have one of these switches gathering dust. I've susomised my lower roller bearing filament guide so this runout sensor fits to it nicely lined up with the filament path between the roller and extruder. You will need only 2x 3mm setscrews with 15mm thread. These hold the runout sensor housing closed and secure the sensor itself securely. You will also need an extended cable which you can buy or make from the redundant Z-stop cable. The filament roller bracket uses the same bearing, roller and bushes from the original, thing number 4835184 Depending on how you orientate the stls in slicer you may need supports but these will be minimal.
