Low Profile End of Material Sensor Mount on for dual drive extruder. This unique assembly clips directly onto a direct drive extruder, enabling the usage of a limit switch as an end of material detector. Originally designed to utilize an old Ender 3 Z limit switch repurposed from a bed level upgrade. For assembling, it requires 2 M4 Socket head cap screws and nuts. It is conveniently attached to the extruder by inserting it into the tube clamp. The design is low-profile to prevent any unnecessary increase in weight and height. This was designed for standard 1.75 dia filament.
