Feature:Stamp size on the surface, convenient to pick the one you need.The hole of the print nozzle is consistent in size and machining, the thread is clean and well-formed.Extruder stainless steel print heads are usually applied to print non-abrasive material filaments such as PLA, ABS, PCL, etc. How to Replace Nozzles?1: Turn on the 3D printer, heat the nozzle and heat block to the target temperature (PLA: 180-220, ABS: 240-280).2: After heat finishing, close the printer, take the spanner to hold the heat block. Then use a socket screwdriver to screw the old nozzle extruder out.Notice: Please don’t touch the old nozzle and heat block.3: Spanner keeps to hold the hear block, use the socket screwdriver screw the new nozzle in, make sure tight.
