CR10 - CR10S - Ender 3 x-limit switch and filament runout mod for direct drive - REMIX

thingiverse

This is a subtle remix of franpoli's filament runout switch/guide mod for the CR10/Ender 3. The change being, the top portion shifts about 5mm to the left to be flush with the x-axis motor cover edge. Also, the right-side sharp corner on the filament sensor box is rounded - although it doesn't appear that way in the photo. The purpose of this remix is to make it more compatible with BoothyBoothy's Hydra Fan Duct setup. During x-axis homing, I discovered the wire bundle would get mashed hard into the sharp edge of the sensor box, which could cause damage to the wiring over time. **UPDATE** I've included a version of the back piece that accommodates M3x6mm SUS303 tapping slotted threaded inserts for better screw gripping. The original design was very prone to stripping.
