Filament Loading Tool for Prusa MMU2.0 Buffer

thingiverse

This is a simple rectangular stick that I modeled to help make the process of feeding filament through one side of the MMU2.0s Buffer to the other much easier. Without it, you will be trying to force filament to go 6"-7" straight across the buffer to the PTFE tube on the other side when all the filament wants to do is curl away in the wrong direction. Because of the buffer's design, you can't get your fingers in there to try and manipulate the filament. So you have to resort to whatever thin tools/objects you have lying around to stick in there and direct the curling filament to try to direct it. It's frustrating work to load 5 rolls of filament through the buffer. So I got tired of it and modeled this 225mm long stick which is just the right size and rigidity to slide in between the buffer sheets and manipulate the filament to its ultimate destination. It works so well in fact, that dealing with the buffer is a totally different experience than when I first set it up. So I thought I'd share it here for anyone else who is struggling to load filament through the MMU2.0s buffer. Let me know if it helped! I fell a bit silly loading a 225mm rectangular prism on Thingiverse. I'd be glad to know if someone else managed to make use of it.
