3d printing problem (please help)


I want to explore 3d printing and have a problem that every time I print (except maybe once for very tiny model) extruder clogs. It is also very difficult to clean up it then. It often clogs inside this transparent tube (close to extruder). I’m using standard provided PLA filament.

Can anyone please help how to resolve, or maybe there are replacement parts or compatible extruder which is better. Anything helps.
