Upgrade Kobra S1 Ceramic Hotend,0.4mm Hardened Steel Nozzle+Heating Block Integrated Structure Hot End Replacement with Silicone Sock Compatible with Anycubic Kobra S1/S1 Combo 3D Printers

Worked great!! Fit perfect Solved my clogging issue instantly. I wasn’t able to print ANYTHING before this product. Heats up super fast and cut my prep time down by more than half. fast overnight delivery at a amazing price! So happy i can finally print

i should have looked at it before the return windo closed. i bought this to have on standby when the other one failed and today it did just that so i went in to switch to this one just to find out it has a pin not push in and i cant even return it. its junk

I picked this up as a replacement/upgrade for my Anycubic Kobra S1, and it works exactly as advertised. The integrated ceramic hotend with the hardened steel 0.4mm nozzle is a big step up from the stock setup. Installation was simple and straightforward, and everything fit perfectly without modification. The heating block design keeps temperatures stable, and the hardened steel nozzle is excellent for handling not just standard PLA and PETG, but also abrasive filaments like wood or carbon fiber without wearing out quickly. The included silicone sock is a nice bonus that helps maintain even heat and reduces filament buildup on the nozzle. So far, my prints have been clean, consistent, and I’ve noticed fewer clogs compared to the stock hotend. Definitely a solid upgrade for anyone looking to get better performance and longevity out of their Kobra S1 or S1 Combo.

Doesn’t work right out of the box. Kobra S1 won’t go past Nozzle Pid Cal
