Prusa Mini Buffer Mk7

thingiverse

In my ongoing pursuit of simplifying the process of loading and unloading filament on the Prusa Multi Material Unit (MMU), I'm thrilled to announce that the project has reached version 7. Previous iterations have focused on mastering the control of filament as it loads and unloads, but Mk7 takes it a step further by incorporating a spool holder that streamlines the process. This design ensures a smooth loading experience, followed by a controlled unloading procedure. For those who prefer a more straightforward approach, I've included an alternative version that omits the spool holder, providing a simple filament buffer solution. To accommodate my MK3 print bed's size, I've maximized the dimensions of both the base and lid. The result is a spacious setup that allows for effortless filament handling. The filament holder itself features a clever cassette design that facilitates easy loading. Once loaded, the cassette can be stored safely inside the base, and the lid securely closed, providing a tidy and organized workspace.
