MK9 Dual-Extruder Assembly Top Cover Plate

 

This Top Cover Plate fits over the MK9 dual extruder assembly on the Duplicator 4S and 4X. This new cover plate has a gap cut into it to compensate for the drive block arm on the MK9 extruder upgrade. Remove the old one and install this new one for a secure and wobble-free extruders assembly.
