Prusa MMU mini buffer MK8

The wheels of progress never stop. The MMU mini buffer hits version 8. This time the design is compact and simple. The cassette from the version 7 is retained but this time the spool sits on the original hardware from the Prusa filament spools.

In terms of hardware, you will need the 5 x 608 bearings, 2 x filament rollers from the original prusa filament spool holder and 3 teflon tube connectors. Oh and a short length of teflon tube to connect the cassette to the spool holder.

printer parts consist of the base, the lid, 2 roller arms, the cassette and the wheel. None of these should require any supports of rafts etc.
