Prusa MMU Mini Buffer Mk2
thingiverse
The Prusa MMU buffer never really impressed me as being very practical, so I decided to design my own. After several iterations, I came up with a mini buffer that's surprisingly effective. Simply connect it to the end of your MMU PTFE tube using a bowden connector, and the filament will effortlessly unspool into a loop. When you need to use the filament again, it simply spools back in, eliminating the need for auto-rewinding spool holders altogether.
