Belted Extruder v4 printed Gear GT2 60 Teeth with Knob

thingiverse

I really like the design of the belted extruder v4. But since I was too impatient to order an aluminum gear, I printed one. The M8 hobbed bolt is simply inserted press-fit and therefore fits extremely tight with no play. In the 2nd iteration, I added a knob so that I can move the extruder by hand. Another big advantage is that you can easily use the hobbed bolt as it is without any modifications. You don't have to saw anything off or make other changes. You only need two washers. I also printed a small washer to get the right distance and let the ball bearing run freely. I modified the gear from Naralex BallMill and combined it with the Extruder Knob from lonewolf78. Thank you both for your designs! I am very satisfied with the result, and I think it can be seen! I added just the knob, one version to put the bolt through and another one that should plug onto the head of the bolt.
