2 hot Ends and 1 Mount Block for BIBO 3D Printer (Version B)

We strongly recommend using the filament or metal stick to dredge the clogged extruder or the stuck filament inside the extruder instead of replacing the parts, so you don't have to disassemble anything. The metal sticks under the diameter 1.75 mm are ok. We can push down the filament or metal stick by hand again and again to the heated extruder to dredge the clogged extruder or the stuck filament, and this way usually works.

SO PLEASE DON'T REPLACE THE PARTS IF YOU HAVEN'T TRIED PUSHING THE METAL STICK AND THE FILAMENT DOWN TO THE HEATED EXTRUDER.

This is VERSION B hot ends assembled together with the long aluminum mouting block for BIBO 2 3d printer. It only fits the VERSION B thermistor
