CR-10s Filament Runout Sensor Frame Mount

thingiverse

Update 14/06//2021: I found the the old version of the mount was a bit sensitive and would on occoasion trigger runout even with filament inside or on filament with larger variances in it's thickness it was possible for the filament to jam in the mount. The new version of the mount has addresses these issues by widening the path for the filament slightly and bringing the channel much close to the switch. Having tested this now for 2 weeks I feel confident sharing it here. Since upgrading my CR-10s to Direct Drive I've not been able to find a good mount for the Filament runout sensor that I liked. So I made one. This is designed to be mounted to the printer frame using standard M5 t-slot bolts (I had some leftover from installing stabilizers on the CR-10s). You will also need two 16mm M3 bolts to keep the cover in place. I also allowed for 2 short lengths of PTFE tubes to act as a filament guide. Printable without supports though you may want to add some from the build plate ones for the nubbins where the PTFE tube slots in. Takes about 2 hours to print depending on settings. While not showing in the pictures I have added a directional arrow to show which way the filament goes in (just in case it wasn't obvious.) Lastly, I have included the step files in case anyone wants to adjust the sizes for the mounting bolts etc.
