This model replaces the original X-axis motor mount/belt cover with one that adds a filament runout sensor. The switch used for this build is a HiLetgo KW12-3 Roller Lever Arm Micro Switch. Also required are 2 standard 4mm Bowden collets. The switch is mounted with 2xM2.5x10mm self-tapping screws.
The updated version of this mount can be printed entirely without supports. The original X-axis endstop mounts to this part using the original screws. If PLA is used, be extra careful when screwing in the endstop, to avoid breaking off the screw bosses. PLA+ or PETG is recommended instead for this reason. Printing at a 0.2mm layer height is HIGHLY recommended, as several of the tolerances are tuned for that layer height, and printing at a different layer height may cause issues with assembly or usage.
