Ender 5 Plus top mount direct drive with BL Touch mount

Update 20200503
I have been using the MG Chemicals version for 2 months with very active printing (covid masks and shields). It is holding up well but I noticed one problem - the extruder motor pushes down when feeding, and up when retracting. This shifts the bracket by a milimeter up and down respectively because it is only attached at one end. No noticeable effect on print quality but movement is bad. Need to figure out a way to lock down both ends of the bracket.
