These brackets replace the standard units that mount the RMU to the MK3/S/+ variants. Due to the larger xBuddy case, more clearance is needed. The location of the RMU moves 15mm towards the rear of the printer. I made these for my MK3.5 upgrade and used the extra M3nEs nut in the kit for the lower bracket mount to the extrusion. These brackets should fit the MK3.9 and MK4 as well. There is also clearance to use the ethernet connection if you choose.
Not sure if it is necessary but I also added a third screw to the top bracket at the frame. Possibly it will help with the faster speeds & vibrations?
