CR10S Filament Sensor

<h2>Creality CR10S Extruder Stepper Motor Mount for Filament Runout Sensor (for use with Micro-Swiss direct-drive extruder)</h2> I recently upgrade to the Micro-Swiss direct drive extruder and all-metal hot end for my CR10S and the previous wobbly filament sensor mount was bugging me. Since the Bowden stepper mount is free when using the direct drive kit, I thought I'd take the Micro-Swiss idea of attaching the PTFE tube and cables from the extruder to this point and add a filament sensor. <h3>Improvements over other sensor housings</h3> Within the main sensor housing there is provision to insert two small lengths of PTFE tubing, to minimise friction and ensure smooth operation. After printing I recommend just using a 4mm drill bit, held in your fingers, to ensure the insert area is clear of any printing defects to ensure easy insertion. I prefer to tap the threads for mounting the PTFE tube clamps, if you print the design with 4 outlines you will get sufficient solid material around the hole to tap into. I recommend printing in translucent PETG as this allows the LED to shine through from the standard CR10S filament sensor board and gives a strong final assembly.
