Geared Extruder using M8 extruder driver

myminifactory

In my ABS printer, which has a frame from an old K8200, I used Geared Extruder 2 and it worked well for a while. The printer's closed housing caused temperatures to rise up to 45°C for hours on end, and the heat bed reached 110°C. This heated situation made the main body of Geared Extruder 2 warp slowly over time, causing the gears to no longer fit together properly. So I created this new extruder specifically for this printer. I reused the old M8 extruder driver that came with the K8200 printer. The filament wire is now pushed against it by two 608Z bearings, which guide it between them. The extruder driver is 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 this time. To make the main body more resistant to the heat, I printed it in gray ABS. With the filament guide, you can now adjust the path of the filament wire as it enters. I still tried to keep the filament wire visible at all times for easy replacement. The small gear has 10 teeth and the large gear has 43 teeth. This extruder can handle 1.75, 2.85, and 3 mm filaments.
