So I decided to mount the MMU2S on the gantry so the PTFE tube going to the extruder can be as short or shorter than it is on the Prusa MK3 with the MMU2S. But I do not want the 5 PTFE tubes to exit the rear of the printer. This can cause interference issues with the heat bed. So I designed this bracket to orient the mmu perpendicular to the gantry..
