Compact Spoolholder with Integrated Buffer

I needed a compact solution for filament management for my Core ONE and MMU3 and I wanted both to be integrated so I didn't have to use the Prusa buffer. This combines a buffer and spool holder into a single compact unit that prints on a standard MK3/4 Core ONE bed. You just need 8 m10 screws to secure the two pieces together and a your Prusa buffer cartridge.

Has plenty of runout if you are using the standard length (710mm) front PTFE tube.

Looks super interesting! The files on Printables seem incorrect though? It seems it's just two copies of the spool holder and the buffer file is empty?

Thanks for fixing the buffer file! What's the difference between the other two files though? They look the same?

RE:

The first file should be both pieces, and the others should be the individual sides.

 

Apparently I had visibility turned off in fusion360 when I exported the model for the first file.  The other two files are the complete model, just individual.
