Cr-10 Extruder mount with filament runout sensor holder & cable management

thingiverse

I set out to move my extruder after purchasing a left-hand extruder by mistake, which damaged the tension arm on the stock extruder. This will move the extruder away from the Z screw, giving more clearance and providing a filament sensor mount that may require adjusting the sensor mount position if you have a right-hand extruder. This remix combines two projects: https://www.thingiverse.com/thing:2991917 and https://www.thingiverse.com/thing:2945390. I've added STL files for the sensor mount, making several changes to get it working. If you're using a right-handed extruder, you'll need to drill three holes to hold the filament sensor in place, as it will be about 5mm out of position. If people want, I can create a different version for the right-handed extruder. If you're unsure about the difference between left- and right-handed extruders, basically, the tension arm is positioned around the other way, with the pinch roller pushing against the opposite side of the stepper motor. For example, a right-hand version pushes against the bottom side of the stepper motor, while a left-hand version pushes against the top, requiring you to reverse the direction of the stepper motor if you've swapped from a right-hand to a left-hand extruder. I reversed the pins in the connection cable from 1234 to 4321 when I switched from a right-hand to a left-hand extruder. Let me know if you'd like me to add a new version with holes aligned for the right-hand extruder.
