This is a modification to the filament buffer kit that comes with the MMU2s.

I think that the original design of the buffer is to much of a hassle to load, since you don't have enough room to grab and push the filament towards the MMU. It's also an open design which lets dust collect inside of the buffer and perhaps contaminate the filament.

So: -I designed this new buffer that re-uses the acrylic plates from the original design. -It's now standing, but that allows it to work as a lid that's easy to load with filament.

Hardware required: -11x M3x40 screws -11x M3 nuts -10x M3x12 screws -Two 20x6x** rectangular magnets (I'm using 1,5mm thick ones, but thicker or double stacking magnets will also work).

When closing the lid, make sure to have the filament in an arch. And slot the filaments in between the plates.
