Review on 🖨️ Creality Additive Manufacturing Products: Optimized Storage Solution for Printer Extruder Nozzles by Bob Fasho

These nozzles were causing clogs and duplicate filaments every time I tried to use them. Some prints could work for an hour or more, after which the filament was fed back into the Bowden tube. (The printer moves in the air - the filament is not extruded). After disassembling my hotend three times, thinking it was a malfunction or user error, I ordered more attachments from another seller. Print new ones with no problems. I just tested the nozzles with different sized cleaning nozzles and found that they are rough on the inside and the nozzle exits are not the same size at all. With some, the 0.4 mm needle goes through, with others not. The needle also grinds or sticks to the roughness inside the nozzle. I cannot recommend these nozzles. I think buyers who love them are lucky because the quality is generally unreliable.
