Prusa Mk3S MMU2S Tower Print Buffer

thingiverse

This is a redesign of the MMU2S Print buffer system to relocate the 5 spools above the printer and a rear mounted vertical buffer system. It saves a lot of space, fitting within a 56cm X 56cm (22" X 22") footprint. It just fits inside an IKEA Lack enclosure that is double stacked (except the Mk3S control panel sticks out a little). It is also far easier to feed new filament. The MMU2S feed tubes are shortened to under 10CM and there is more space for fingers to feed filament to the MMU2S rollers. The feed from the spools is also relatively easy with a large space for hands to get in and work. This solution has been tested with PLA, ABS, and PETG. TPU also works but has not been thoroughly tested. Any material that can be curled into a 9cm (3.5") diameter circle should work.
