Is there any model to print the extruder gear of the a1 mini?

[megatolusalen]

The extruder is having troubles to print because the two gears arent able to push the filament. They cant hold it tight enough… I am wondering if someone has a model to 3d print it? I can still print if I push manually during the print. Otherwise I need to pay 20 euro to bambulab. My extruder cant push the filament. Only when I push the lever in the left it goes out. When I don’t do it, it seems like the two gears cant hold it and it just moves without doing much… Could cleaning the gear or replace it fix it?
