ALAMSCN 12PCS V6 Volcano Brass Nozzle Kit 0.2mm 0.4mm 0.6mm 0.8mm Extra Extruder Nozzles 0.4mm M6 1.75mm Filament for 3D Printer Part

Tried the .8, .6, and .4 mm nozzles and all 3 didnt hold up. Started showing signs of wear and over extrusion by only 100 grams of standard PLA+. No abrasives were run at all. Pretty poor quality.

No complaints, as advertised.

Exactly what I needed. Haven’t had any issues.

These are acceptable substitutes in a Sidewinder X2. However, the shafts are just one or two millimeters shorter than the stock nozzles. This leaves a gap between the PTFE tubing and the nozzle rear which fills up with molten filament and clogs. You can fix this by putting in a new PTFE tube, but this makes a two minute nozzle change task into a twenty minute hotend disassembly.
