Geared Extruder using M8 extruder driver

cults3d

I modified my ABS printer's frame from an old K8200 and used Geared Extruder 2 with great success for a while. The closed housing of this printer allows temperatures to reach up to 45°C for hours on end, along with the heat bed reaching 110°C. This caused the main body of Geared Extruder 2 to warp over time, making it impossible for the gears to fit together properly. To address this heated situation, I designed a new extruder specifically for this printer. I reused the old M8 extruder driver that came with the K8200 printer and used two 608Z bearings to guide the filament wire against it. The extruder driver is now held in place on both sides, preventing the main body from bending. Additionally, I made it possible to adjust the distance between the motor and the large gear. To enhance the main body's resistance to constant heat, I printed this new design in gray ABS. With the filament guide in place, adjusting the path of the filament wire is now a breeze. For added convenience, I designed the extruder to allow for easy visual inspection of the filament wire, making it simple to swap out when needed. The small gear has 10 teeth and the large gear boasts an impressive 43 teeth. This Extruder can handle filaments with diameters of 1.75mm, 2.85mm, and 3mm.
