This a rework of Mahor's pellet extruder v3. Aiming to overcome the following challenges: Stability - the original design is a bit wobbly and flexible when mounted to the CR10, you can see in some of Maho's videos he has used aluminium to make the front and back plates, but as I don't have the tools to do this I wanted a 3D printed solution. Dust and mess - if your active cooling is blowing air into the hopper and your printing with shredded wast plastic then you end up with bits of plastic getting blown everywhere. I wanted a different location for cooling (this is not a problem with pellets). Prevent blockage - shredded wast plastic is very high friction and the pieces of it are very light so it dose not flow very well. Make it easy to mount to my CR10 - now it mounts directly.
