Spool Holder For MMU

A major issue when using MMUs is the footprint. Many people would have difficulty finding space for a filament buffer, a total of 5 kg of filament, and Prusa. Therefore, we thought it was necessary to create a spool holder that could hold 5 kg of filament in the frame of the Prusa.
We designed a holder in which two 1 kg spools are mounted avoiding the MMU. With two of these, a total of 4 kg of filament can be mounted. Furthermore, using the spool holders that Prusa has made available, a total of 5 kg of filament can be mounted on top of Prusa.
This enables the MMU to be operated in a space-saving manner.

Only the mounting part to the frame was diverted.
