Geared Extruder using M8 extruder driver

In my ABS printer (frame is of an old K8200) I used Geared Extruder 2 and it worked very well for a while. This printer has a closed housing and the temperatures go up to 45°C for hours and hours. Also there’s a heat bed that reaches 110°C. This made the main body of Geared Extruder 2 to warp slowly and the gears wouldn’t fit into each other anymore.
So for this heated situation I made this new extruder just for this printer.
I used the old M8 extruder driver that came with the K8200 printer again. The filament wire is pushed against it by 2 608Z bearings this time, so it is guided between them. The extruder driver is held on 2 sides this time, so the main body can’t bend. Also I made it possible to adjust the distance between the motor and the big gear this time. To make the main body more resistant to the endless heat I printed this one in gray ABS. With the filament guide it is possible to adjust the path of the filament wire going in. I still tried to make it able to see the fil
